Why does clojure do worse than scala in the alioth benchmarks. Scala is more likely to be "the next Java", while it's hard to imagine that Lisp will finally take off after not doing so for over 50 years. Mais ce n’est pas le cas, même si vous le pensez. "scripting language embedded in Java". Joy of Clojure - Questions. I meant the comment towards Ryan Delucchi. Scala vs Java Performance – Welcome to the Ultimate battle of the Century. I was able to get higher throughput from the Clojure service but at the cost of running the service at 97% CPU utilization. Although Scala's static typing would normally translate into a speed advantage over Clojure's duck typing, Clojure does support type hinting which can speed up code considerably. Although Scala's static typing would normally translate into a speed advantage over Clojure's duck typing, Clojure does support type hinting which can speed up code considerably. I realize that this will vary from one language feature to another but an general assessment of performance would be helpful. Clojure vs Scala - anecdote Showing 1-22 of 22 messages. Clojure vs Scala for High Performance Web API. Syntactically, it's also the furthest of the three languages from typical Java code. Ultimately, if it is a close enough draw between clojure and scala, I might try them both. Just because both use a bytecode does not mean the implementations will have even remotely comparable performance. Four of the five top paying languages are the functional programming languages Clojure, F#, Scala and Elixir. But it isn't, even if you think it is. Some pain points might be some edge cases of dealing with Java's generics, because Scala's type system is much stronger than Java's. clojure vs scala. ... Clojure, and Scala. What to do? Clojure is a functional language in the LISP family, it's also dynamically typed. How do I read / convert an InputStream into a String in Java? Therefore, most data will be immutable by default. Both Scala and Clojure sit easily on top of Java. Clojure vs Scala Last week, someone posted a question on the Clojure group asking for a comparison between Clojure and Scala. Dynamic languages that need to stay interoperable with a static languages like Java are, @julkiewicz - it is simply not true that dynamic languages are. Features such as STM support give it some of the best out-of-the-box concurrency support, whereas Scala requires a 3rd-party library such as Akka to duplicate this. Clojure code does not necessarily have to be slower than Java or Scala. Active 8 years, 5 months ago. Caught someone's salary receipt open in its respective personal webmail in someone else's computer. This page is powered by a knowledgeable community that helps you make an informed decision. Clojure may appear to be simple. Published at DZone with permission of Gary Sieling, DZone MVB. He says that Scala is a "scripting language embedded in Java", which I don't buy. That said, it's pretty easy to submit anything--it's all open source. People asked about a few other languages as well, so let's get them out of the way first. As both Scala and Java are essentially class-based languages, they interoperate more easily. First off, a language isn't inherently slower than another but "equivalent" programs may have different performance characteristics. Clojure is a functional language in the LISP family, it's also dynamically typed. How to make sure that a conference is not a scam when you are invited as a speaker? Scala et Clojure s’assoient facilement au-dessus de Java. It is written neither in scala- nor clojure- apologist manner but rather in truthiness way. Another example: Run Java, Clojure 1.3, Clojure 1.4 alpha1, and Clojure 1.4 alpha3 versions of all of the benchmark programs. Regarding interop w/ Java, Scala is closer to Java but I'm sure both languages interoperate well. Clojure wins because: Scala. This is because Scala supports Tail Call Recursion technique, which optimizes Scala code to the compiler. 15 replies Clojure. Most of a … I learned scheme first, then haskell, then (now) clojure. Si votre code est critique en termes de temps ou d’espace, restz fidèle à Java. It is pretty difficult to optimize the byte code in Clojure and hence the performance of Scala is better in terms of byte code. Calling Java code and extending Java classes/interfaces works the same way as calling Scala code. Difference Between Scala vs Java Performance. My understanding is that you can use these features when you need it to get speed equivalent to writing exactly the same code in pure Java. But both Scala and Clojure are JVM languages so they should have similar performance. Scala versus The Almighty Java. -1 "both Scala and Clojure are JVM languages so they should have similar performance" makes absolutely no sense. It may run five times slower than Java, but the source is five times smaller (YMMV). Also using traits with non-abstract methods from Java should be complicated, and calling methods with special characters would require knowing how they are encoded in the bytecode. SVN claims to be "CVS done right". It is trivially easy to call Java from Scala. How to create a geometry generator symbol using PyQGIS. albeit complex type system. Why not try them both? Proof? Most of a program's run time is generated by a small amount of the actual code. Scala on the other hand is much closer to Java. A quick perusal of eFinancialCareers technology jobs confirms the results of this survey - there just aren’t that many roles for functional languages. Neither sits well underneath it. Clojure is nothing like Java. express it. Clearly you haven't used Clojure. A: That all depends. Join the DZone community and get the full member experience. % ./run-all.sh long java clj-1.3 clj-1.4-alpha1 clj-1.4-alpha3 (5) If you want all results recorded to an XML file, look in env.sh for MP_COMMON_ARGS and the … Clojure, Kotlin, and Scala are probably your best bets out of the 14 options considered. You'll gain Viewed 2k times 11. Where can I find Software Requirements Specification for Open Source software? How would a theoretically perfect language work? How are you using Clojure? In my view, Scala is Java done right. 15 replies Scala. Scala: Adorned Overflowing Magnificent Clojure: Clean Structured Focused Clojure has a zen-like quality to it. Possibly, ordinary Scala is faster than ordinary Clojure, but you only need to optimize the bottlenecks. Compare Kotlin vs scala to see which JVM language is a better Java alternative. multiply by hundreds of millions .. How do I convert a String to an int in Java? How would you gracefully handle this snippet to allow for spaces in directories? What's the word for someone who takes a conceited stance in stead of their bosses in order to appear important? By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. Performance and Scalability. rev 2021.1.18.38333, Stack Overflow works best with JavaScript enabled, Where developers & technologists share private knowledge with coworkers, Programming & related technical career opportunities, Recruit tech talent & build your employer brand, Reach developers & technologists worldwide, With Clojure 1.2 Clojure can call java without overhead. Scala or Clojure Functional Programming best practices. All I have read so far is that Scala has native collections types that make it a bit clumsy to integrate with a large Java code-base, whereas Clojure follows a simple Iterable/Iterator-centric way to inter-operate with Java classes. So, if Clojure is significantly slower: I'd like to know sooner rather than later. Why did the design of the Boeing 247's cockpit windows change for some models? On interoperability, I can't speak for Clojure, but I would expect it to be in a similar situation as Scala. people claiming Clojure as a skill – surprisingly beating out Scala’s 9%, a surprising feat for a lisp-variant. Developer Scala vs Clojure: Performance (Speed) Scala is fast. La Scala idiomatique est plus rapide que la Clojure idiomatique et le restra. Scala has a few implementation advantages over Clojure and I would expect somewhat higher performance. 2-25x slower than Java, 2-30x more memory and code size is generally larger than Java. Clojure. Possibly, ordinary Scala is faster than ordinary Clojure, but you only need to optimize the bottlenecks. For most of most applications, this is a big win. To learn more, see our tips on writing great answers. At first, I was in the mode where I wanted to just pick one and run with it. It’s great! Clojure is, in many ways, a better language, and it certainly has very interesting features not present (so far) on Scala, but you reap such benefits by going fully functional. But for some, and for some parts of many others, it's a devastating loss. after ~1 year with it, I've decided that haskell, while great, is not for me, and I'm switching over to clojure. LinkedIn shows 42% growth (year over year?) The language, also, can be to blame. :-). And I'd like to add that I do have a bit of a "soft spot" for LISP so the fact that Clojure suffers from parethesitis isn't enough to scare me away. Functional and sequence abstractions do not appear. There is no such thing as Clojure lite: writing Java idioms in Ni l’un ni l’autre ne se trouve bien en dessous. Firstly understand that Racket and Clojure are both in the Lisp family but were created and developed for very different reasons. Table of Content. Scala vs Java. Marketing Blog. Benefits? Possibly, ordinary Scala is faster than ordinary Clojure, but you only need to optimize the bottlenecks. Features such as STM support give it some of the best out-of-the-box concurrency support, whereas Scala requires a 3rd-party library such as Akka to duplicate this. When comparing Python and Java, it seems a bit unreasonable to blame the language for the speed difference. Sur la Performance et L'interopérabilité Java: Clojure vs. Scala j'ai déjà lu divers comptes rendus de Clojure contre Scala et tandis que je me rends compte que les deux ont leur place. 6. Any more thoughts/details on this? Looks like it's comparable to Python where Scala is very close to Java. functional + object oriented + actors + familiar syntax; this seems great until you realize how complex it makes things. You can go for Scala lite: writing Java idioms in Scala. Rather than waiting for functional features to appear in the JDK, many developers are switching to more functional-friendly JVM languages, such as Scala, Kotlin, and Clojure. Il y a quelques considérations que je n'ai pas acquises une explication complète sur quand il vient à comparer les deux Clojure avec Scala: With Clojure you get a minimal code-size, parallelized computations and blazing performance that?s 72% faster than Ruby and 36% faster than Scala. With the present JVM Scala has an advantage on the account of being statically typed, as JVM support for dynamic typing -- reflection -- is slow. Not so with Scala. With Clojure, you compile down to Java Byte Code when you run your application or library. Heck! Calling Scala from Java is most of the time straightforward, but for example Scala's companion objects requires knowing how they are compiled to bytecode. Why is “HADAT” the solution to the crossword clue "went after"? Scala classes may compile to a number of classes with names that look funny in Java. It's now (as of May 2010) worth loking at the latest 1.2 branch of Clojure - this includes a lot of additional support for primitive types and static typing (through various type hints and protocols). If your code is time-critical or space-critical throughout, stick to Java. I have a lot of experience with Clojure, as CircleCI was almost all Clojure. Clojure is about as Object-Oriented as Scala is Functional. Clojure vs Racket: What are the differences? Functional programming. There you go. Scala gives you a somewhat bloated code-size, but in return you get about than 50% more performance out of your system. Clojure is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Should I hold back some ideas for after my PhD? Thanks for contributing an answer to Stack Overflow! Is Java “pass-by-reference” or “pass-by-value”? Scala is functional in the broadest sense of the word: It has immutable constructs. But it's clear that Lisp is on its own unique level of abstraction, and Clojure is fairly simple, so Scala + Clojure won't be that much harder than just (the rather complex) Scala and I'm sure you will be glad you did it. Performance is a question that comes up quite often on the Clojure mailing list and folks usually jump in to show how to create an idiomatic version of the code that runs at "native" speed compared to the (closest) equivalent Java. How do I efficiently iterate over each entry in a Java Map? The November 2010 issue of PragPub discusses Clojure-Java interoperability. In Programming Clojure Stuart Halloway writes: "[you can access] anything you could reach from Java code.". Scala is the way to go. Scala has a few implementation advantages over Clojure and I would expect somewhat higher performance. Scala has a few implementation advantages over Clojure and I would expect somewhat higher performance. Although Scala's static typing would normally translate into a speed advantage over Clojure's duck typing, Clojure does support type hinting which can speed up code considerably. Those things exist in Clojure for interoperability with Java, but classes and objects are clearly not main features of Clojure. Clojure definitely emphasizes Functional Programming over Object Orientation and Scala is just the opposite. You would be hard-pressed to pick two better languages, though I like Ruby also. When I moved from Java to Python, I fell in love with Mutable Dictionaries. Which of the two languages is generally faster? This answer sheds good light on the true differences and strengths/weaknesses of the two. How is interoperability with Java? Look at, Huh. And since Scala author Martin Odersky wrote Sun's Java compiler, I kinda think no balls have been dropped on the Scala side, either. Efficient way to JMP or JSR to an address stored somewhere else? In my opinion, the features and concepts of a language (functional, OO, ...) are much more important criteria for choosing a language than the performance (of a particular implementation of that language) - altough I understand that you don't want to get trapped into a language for which there is no well-performing implementation available. Problems might arise when it comes to Scala's singletons or Java's static members, particularly when there's a framework involved expecting things to work in a certain way. These languages are at the very bottom of the popularity scale in the same survey. I have already read various accounts of Clojure vs. Scala and while I realize that both have their place. Why not Clojure/Haskell/Scala? (. If you don't, then you should probably stay with Scala. that Clojure can generate code very similar to statically typed languages using type hints. Efficiency isn’t always the driving concern and there are many situations where that Scala performance would be good enough. Why are you worried about which one to try? The immutable data and STM features that are core to the clojure language are something not available in core Scala, and they make it. I’d say the most important are these : Racket is an evolution of Scheme. Clojure Clojure for teams. The Computer Language Benchmark Game sheds little light on Clojure's true resource costs. Nov 09, 2017 Performance nemesis: reflection. I already have Python at my side for doing quick-and-dirty tasks. You can implement an interface, extend a class, declare private and static functions, etc. @javadba The idea that clojure is bad for low-level multithreaded code seems pretty arbitrary. Though app performance depends highly on the nature of the app, let’s consider an Android application for comparison of JVM languages. Please justify. Clojure is utterly pointless. You don't create classes and design your project in an OO way if you're going to program in Clojure. Creating getters and setters following the Java Bean convention requires an annotation. (Unless he meant Clojure, which I have no idea about). "Surely this is more valuable than the few ms of runtime" .. That depends on the scale of the data. Problem is: what happens when - deep in a project - you discover that your performance is poor - and not due to just one small piece of it (which you had already planned to convert to java for that very reaon). The reason is because Scala is not exactly Java. A comparison of Clojure and Scala for implementing a web API. State change is handled by functions (for transformations) and atoms (an abstraction that encapsulates the idea of some entity having an identity). Clojure programmers are highly encouraged to use immutable data in their code. Improve INSERT-per-second performance of SQLite. some brevity, a syntax that's easier on the eye, and a coherent Note that Clojure and Scala are two totally different types of programming languages - Clojure is a functional Lisp-like language, it is not object oriented. your coworkers to find and share information. You might say that it is Lisp done right - a bold, some would say preposterous, claim - which may turn out to be true. 7 replies Clojure. If you want to mutate transients for example and one of those is accessed from an outside thread, you get an exception. The language constructs of Clojure performs very well when compared with Scala due to transactional memory and persistent data structures. >> "than the performance " . Clojure is a compiled language - it compiles directly to JVM bytecode, yet remains completely dynamic. Has the Earth's wobble around the Earth-Moon barycenter ever been observed by a spacecraft? 8 replies Clojure. There are a few considerations that I haven't acquired a complete explanation on when it comes to comparing both Clojure with Scala: 1.) I think either language will be fast enough for you. However, we spent a whole lot of time with dealing accidental complexity, specifically "what type is this field" and nulls all over the place. Some people may even ask why? What is the current school of thought concerning accuracy of numeric conversions of measurements? Also, Scala accepts mutable objects just fine, and some algorithms are just faster to implement with mutability. But, I know that Scala is fast (based on multiple personal accounts). A Java class is a class to Scala, and a Scala class is a class to Java. Comments above are somewhat outdated - As of mid-2012 Clojure has closed the gap substantially it's now only about 2x Java on average. Syntactically, it's also the furthest of the three languages from typical Java code. So, perhaps I'll pick both and do a fast-walk with them :-). See the original article here. Say, the input string contains a = character, and you have to grab everything to the left of it, drop all non-letter characters, and change the case of all letters inside. I'd say Scala is a pretty clear winner and Clojure is significantly slower--unless the Clojure test was poorly written. Clojure. Clojure is functional and pure, it protects you. But for some reason, it didn't occur to me that I could just use both and have them inter-operate. Stack Overflow for Teams is a private, secure spot for you and @Daniel: Sorry for confusion. Building component in Scala or Clojure that uses lots of Java libraries is very feasible. Like I said, totally common and makes plenty of sense. You lose the ability to do duck-typing on the arguments to a function. * dalvik (android's JVM) got a JIT compiler in 2.2 version in 2010. I don't want to go with Clojure and run into this problem down the road. Some may even say that Scala is infact a part of Java itself, then why this scala vs java comparison? 5 replies Scala. I'm reaching the point where: if I'm not coding something in a functional fashion - why am I bothering with a scripting language embedded in Java anyway? With experience of the Clojure language, I believe it is possible to tell in advance whether your problem will cleave cleanly into a part that can be succinctly and adequately (in performance terms) expressed in Clojure and a part that needs doing in Java. It can get work done even faster than Java. A lazy sequence is implemented in Clojure while in Scala it is not implemented. The new Scala books are here!!! LinkedIn shows 42% growth (year over year?) 17 replies Clojure. For example, a Scala object is used in some ways like static methods in Java, but it's not the same thing. Or, perhaps, more seamlessly. Scala has been said to be Java done right. One thing about Clojure is the language seems very simple. It seems that the benchmark does covers Clojure now (OP's remark is one year old). Actually the collections of Clojure are git-ish, On Performance and Java Interoperability: Clojure vs. Scala, http://www.codecommit.com/blog/java/interop-between-java-and-scala, Podcast 305: What does it mean to be a “senior” software engineer. You get the benefits and performance optimizations of a compiled language, but can treat it like an interpreted language when developing. Opinions expressed by DZone contributors are their own. The original JRuby had abysmal performance because it was an interpreter that was compiled to the JVM, not the source code. They are in-depth and you can compare many languages. TL;DL; Intro; Goals; Building Web API. You can of course call into this component from Java, but what you are not going to want to do is try to consume a Scala API intended for use by Scala programs from Java. The type system in Scala is Turing complete. It's not always true that a language written in the JVM will perform at top speed. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. And the results are not encouraging. The stats do say that Scala is pretty damn quick. But then again, Scala has a very flexible type system. I introduced Scala based on the promises of performance, concurrency and type safety - and conciseness (especially with XML being a native data type in Scala). to understand because it cuts across the grain of the idioms used to 2.) While I am not intending here to say "do not use clojure - period .." it should be clear that clojure is a bigger risk in the performance arena. It is easy to call Scala from Java as long as you conform your external API to the common points between Scala and Java. Imagine a very common situation — you need to write a string-processing function. people claiming Clojure as a skill – surprisingly beating out Scala’s 9%, a surprising feat for a lisp-variant.... Scala vs. Clojure - DZone Performance Calling Java methods is straightforward, but extending Java classes/interfaces is quite different. The functional programming features of clojure are the most compelling reason why I am considering this language. I'd go for Scala, because it is object oriented but also allows you to learn functional programming (if you're interested in that). 7 replies 1. The stats produced by the "Computer Language Benchmark Game" are about the best you're probably going to find. Of course, as soon as you add type hints, the code is no longer dynamically typed, but rather statically type. All you'll get is slow Java that's hard a few ms is fine for a few records. Making statements based on opinion; back them up with references or personal experience. LinkedIn refuses to show counts for Java- but check out the number of people claiming Eclipse expertise – the company list fits nicely as well. site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. Why do jet engine igniters require huge voltages? When to use LinkedList over ArrayList in Java? Replacing a 32-bit loop counter with 64-bit introduces crazy performance deviations with _mm_popcnt_u64 on Intel CPUs. It’s a touchy subject, as in the one hand Scala and new architecture helped to gain a performance boost from 200–300 RPS per host to around 10,000–20,000 RPS per … "Immutability as the default" is the primary reason people pick Clojure over the competition. In fact, one Scala feature which must be implemented through the same techniques, structural types, is often warned against for this very reason. Scala; TL;DR. Scala & Clojure run on the JVM and compete for a replacement for Java. Developers describe Clojure as "A dynamic programming language that targets the Java Virtual Machine".Clojure is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. So I'd go with Scala on both these accounts. No Clojure data structures are employed. Scala-Java interoperability is elaborated at http://www.codecommit.com/blog/java/interop-between-java-and-scala. Most of a … Join Stack Overflow to learn, share knowledge, and build your career. Over a million developers have joined DZone. Turns out LinkedIn’s default view is misleading – Scala shows more new adopters (2.4k) vs  1.5k for Clojure. Why is the expense ratio of an index fund sometimes higher than its equivalent ETF? Ask Question Asked 8 years, 5 months ago. I think haskell is best for teaching functional programming because it's purely functional and puts focus on that aspect rather than on performance benefits of being functional. For example: I know that Python dictionaries are really fast. Since my most popular blog post, by far, is my Racket vs Clojure post from three years ago, I thought it would be good to post my response here.Ten years ago, I would have said that my ideal dream language is one that provides the flexibility to program in any style. Java is compiled JIT (except on mobile devices*) whereas Python is interpreted. I did a lot of self-study coding, got some experience with Parallel Programming Models: Actors, Software Transactional Memory, Data Flow. There are plenty of opportunities for application level code for which that does not matter: but also plenty of framework / multithreading/processing intensive code bases where that would be a liability. Clojure is designed such that multi-threaded programming mistakes are very hard to make. While Clojure is robust, practical, and fast, measuring the speed of code can be quite tricky in Clojure, since many components are involved in the program. Would coating a space ship in liquid nitrogen mask its thermal signature? How do I generate random integers within a specific range in Java? Scala is an object oriented language which has functional programming features. If you intend to do that, then Clojure is very likely better. Asking for help, clarification, or responding to other answers. Example? But the real basis for comparison should be in performance which is why you should check out my next blog where I put the two micro-services under … On the other hand, if you don't care about OO and you want to learn "pure" functional programming, try Clojure. Statically typed languages are often easier to optimize than dynamic languages, etc. It isn't, but it is expressive. You will not want to mix and match much. > Rust is faster than Java, and Clojure can only ever match Java in performance, not exceed it. Classes Vs Data. But as a whole, it is a much slower language than Java. The major difference is where Kotlin is streamlined version of Java, scala is completely different.
