clojure vs scala performance

Looks like it's comparable to Python where Scala is very close to Java. SVN claims to be "CVS done right". Replacing a 32-bit loop counter with 64-bit introduces crazy performance deviations with _mm_popcnt_u64 on Intel CPUs. Clojure vs Racket: What are the differences? >> "than the performance " . At first, I was in the mode where I wanted to just pick one and run with it. Scala has a few implementation advantages over Clojure and I would expect somewhat higher performance. Creating getters and setters following the Java Bean convention requires an annotation. Dynamic languages that need to stay interoperable with a static languages like Java are, @julkiewicz - it is simply not true that dynamic languages are. With Clojure you get a minimal code-size, parallelized computations and blazing performance that?s 72% faster than Ruby and 36% faster than Scala. Clojure is nothing like Java. 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. Ultimately, if it is a close enough draw between clojure and scala, I might try them both. The new Scala books are here!!! Joy of Clojure - Questions. 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. The stats produced by the "Computer Language Benchmark Game" are about the best you're probably going to find. A Java class is a class to Scala, and a Scala class is a class to Java. Scala has been said to be Java done right. You get the benefits and performance optimizations of a compiled language, but can treat it like an interpreted language when developing. 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 … He says that Scala is a "scripting language embedded in Java", which I don't buy. Calling Java methods is straightforward, but extending Java classes/interfaces is quite different. Active 8 years, 5 months ago. (Unless he meant Clojure, which I have no idea about). Opinions expressed by DZone contributors are their own. When I moved from Java to Python, I fell in love with Mutable Dictionaries. * dalvik (android's JVM) got a JIT compiler in 2.2 version in 2010. Firstly understand that Racket and Clojure are both in the Lisp family but were created and developed for very different reasons. Most of a … Performance and Scalability. Clojure programmers are highly encouraged to use immutable data in their code. Most of a program's run time is generated by a small amount of the actual code. Clojure wins because: Scala. See the original article here. Clearly you haven't used Clojure. But for some reason, it didn't occur to me that I could just use both and have them inter-operate. "Surely this is more valuable than the few ms of runtime" .. That depends on the scale of the data. Marketing Blog. And the results are not encouraging. It seems that the benchmark does covers Clojure now (OP's remark is one year old). Efficient way to JMP or JSR to an address stored somewhere else? Stack Overflow for Teams is a private, secure spot for you and Why did the design of the Boeing 247's cockpit windows change for some models? Scala on the other hand is much closer to Java. I learned scheme first, then haskell, then (now) clojure. 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. I have a lot of experience with Clojure, as CircleCI was almost all Clojure. Scala or Clojure Functional Programming best practices. It is trivially easy to call Java from Scala. Syntactically, it's also the furthest of the three languages from typical Java code. 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. There you go. I think either language will be fast enough for you. Join Stack Overflow to learn, share knowledge, and build your career. La Scala idiomatique est plus rapide que la Clojure idiomatique et le restra. Clojure is a functional language in the LISP family, it's also dynamically typed. Scala is the way to go. 8 replies Clojure. Scala-Java interoperability is elaborated at http://www.codecommit.com/blog/java/interop-between-java-and-scala. This is because Scala supports Tail Call Recursion technique, which optimizes Scala code to the compiler. Scala is functional in the broadest sense of the word: It has immutable constructs. 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. Of course, as soon as you add type hints, the code is no longer dynamically typed, but rather statically type. Why are you worried about which one to try? How would you gracefully handle this snippet to allow for spaces in directories? It is written neither in scala- nor clojure- apologist manner but rather in truthiness way. I don't want to go with Clojure and run into this problem down the road. This page is powered by a knowledgeable community that helps you make an informed decision. Or, perhaps, more seamlessly. With the present JVM Scala has an advantage on the account of being statically typed, as JVM support for dynamic typing -- reflection -- is slow. that Clojure can generate code very similar to statically typed languages using type hints. Another example: Run Java, Clojure 1.3, Clojure 1.4 alpha1, and Clojure 1.4 alpha3 versions of all of the benchmark programs. They are in-depth and you can compare many languages. 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. Like I said, totally common and makes plenty of sense. % ./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 … 7 replies Clojure. How are you using Clojure? Making statements based on opinion; back them up with references or personal experience. If you intend to do that, then Clojure is very likely better. A quick perusal of eFinancialCareers technology jobs confirms the results of this survey - there just aren’t that many roles for functional languages. It is easy to call Scala from Java as long as you conform your external API to the common points between Scala and Java. 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. As both Scala and Java are essentially class-based languages, they interoperate more easily. On interoperability, I can't speak for Clojure, but I would expect it to be in a similar situation as Scala. Proof? > Rust is faster than Java, and Clojure can only ever match Java in performance, not exceed it. With Clojure, you compile down to Java Byte Code when you run your application or library. 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. 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. Difference Between Scala vs Java Performance. @Daniel: Sorry for confusion. 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. Asking for help, clarification, or responding to other answers. 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. 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. 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. Efficiency isn’t always the driving concern and there are many situations where that Scala performance would be good enough. Join the DZone community and get the full member experience. LinkedIn shows 42% growth (year over year?) 15 replies Clojure. The immutable data and STM features that are core to the clojure language are something not available in core Scala, and they make it. Ask Question Asked 8 years, 5 months ago. functional + object oriented + actors + familiar syntax; this seems great until you realize how complex it makes things. ... Clojure, and Scala. Please justify. Therefore, most data will be immutable by default. 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. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. In Programming Clojure Stuart Halloway writes: "[you can access] anything you could reach from Java code.". So, perhaps I'll pick both and do a fast-walk with them :-). Example? But it isn't, even if you think it is. For example, a Scala object is used in some ways like static methods in Java, but it's not the same thing. The reason is because Scala is not exactly Java. Caught someone's salary receipt open in its respective personal webmail in someone else's computer. 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. Clojure is utterly pointless. In fact, one Scala feature which must be implemented through the same techniques, structural types, is often warned against for this very reason. Calling Java code and extending Java classes/interfaces works the same way as calling Scala code. Imagine a very common situation — you need to write a string-processing function. after ~1 year with it, I've decided that haskell, while great, is not for me, and I'm switching over to clojure. How is interoperability with Java? This answer sheds good light on the true differences and strengths/weaknesses of the two. Scala et Clojure s’assoient facilement au-dessus de Java. Scala classes may compile to a number of classes with names that look funny in Java. The major difference is where Kotlin is streamlined version of Java, scala is completely different. Table of Content. Clojure vs Scala for High Performance Web API. Why does clojure do worse than scala in the alioth benchmarks. To learn more, see our tips on writing great answers. The functional programming features of clojure are the most compelling reason why I am considering this language. 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. The problem is that they don't cover Clojure :(. a few ms is fine for a few records. Clojure. :-). However, we spent a whole lot of time with dealing accidental complexity, specifically "what type is this field" and nulls all over the place. Functional and sequence abstractions do not appear. 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. These languages are at the very bottom of the popularity scale in the same survey. 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. Over a million developers have joined DZone. Is Java “pass-by-reference” or “pass-by-value”? You lose the ability to do duck-typing on the arguments to a function. I have already read various accounts of Clojure vs. Scala and while I realize that both have their place. I’d say the most important are these : Racket is an evolution of Scheme. your coworkers to find and share information. But for some, and for some parts of many others, it's a devastating loss. 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). It can get work done even faster than Java. You can go for Scala lite: writing Java idioms in Scala. Scala has a few implementation advantages over Clojure and I would expect somewhat higher performance. Four of the five top paying languages are the functional programming languages Clojure, F#, Scala and Elixir. Clojure is a functional language in the LISP family, it's also dynamically typed. Syntactically, it's also the furthest of the three languages from typical Java code. Most of a … Ni l’un ni l’autre ne se trouve bien en dessous. I did a lot of self-study coding, got some experience with Parallel Programming Models: Actors, Software Transactional Memory, Data Flow. The language, also, can be to blame. Scala versus The Almighty Java. There are a few considerations that I haven't acquired a complete explanation on when it comes to comparing both Clojure with Scala: 1.) First off, a language isn't inherently slower than another but "equivalent" programs may have different performance characteristics. On the other hand, if you don't care about OO and you want to learn "pure" functional programming, try Clojure. Mais ce n’est pas le cas, même si vous le pensez. 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. The Computer Language Benchmark Game sheds little light on Clojure's true resource costs. albeit complex type system. So I'd go with Scala on both these accounts. You might say that it is Lisp done right - a bold, some would say preposterous, claim - which may turn out to be true. Why not try them both? Why is “HADAT” the solution to the crossword clue "went after"? 2.) It isn't, but it is expressive. Possibly, ordinary Scala is faster than ordinary Clojure, but you only need to optimize the bottlenecks. Statically typed languages are often easier to optimize than dynamic languages, etc. How do I generate random integers within a specific range in Java? Well, thanks for all of the insights. Compare Kotlin vs scala to see which JVM language is a better Java alternative. Why is the expense ratio of an index fund sometimes higher than its equivalent ETF? How would a theoretically perfect language work? But as a whole, it is a much slower language than Java. 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. For example: I know that Python dictionaries are really fast. Should I hold back some ideas for after my PhD? Classes Vs Data. 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. Though app performance depends highly on the nature of the app, let’s consider an Android application for comparison of JVM languages. Just because both use a bytecode does not mean the implementations will have even remotely comparable performance. express it. It is pretty difficult to optimize the byte code in Clojure and hence the performance of Scala is better in terms of byte code. Benefits? Clojure is functional and pure, it protects you. Heck! Clojure is a compiled language - it compiles directly to JVM bytecode, yet remains completely dynamic. But then again, Scala has a very flexible type system. 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. I realize that this will vary from one language feature to another but an general assessment of performance would be helpful. There is no such thing as Clojure lite: writing Java idioms in people claiming Clojure as a skill – surprisingly beating out Scala’s 9%, a surprising feat for a lisp-variant. That said, it's pretty easy to submit anything--it's all open source. 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. You would be hard-pressed to pick two better languages, though I like Ruby also. 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. A comparison of Clojure and Scala for implementing a web API. LinkedIn shows 42% growth (year over year?) Scala gives you a somewhat bloated code-size, but in return you get about than 50% more performance out of your system. Viewed 2k times 11. Turns out LinkedIn’s default view is misleading – Scala shows more new adopters (2.4k) vs  1.5k for Clojure. 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. It’s great! So, if Clojure is significantly slower: I'd like to know sooner rather than later. Those things exist in Clojure for interoperability with Java, but classes and objects are clearly not main features of Clojure. Look at, Huh. I meant the comment towards Ryan Delucchi. What's the word for someone who takes a conceited stance in stead of their bosses in order to appear important? Some people may even ask why? 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 … Possibly, ordinary Scala is faster than ordinary Clojure, but you only need to optimize the bottlenecks.
