clojure vs scala performance

Asking for help, clarification, or responding to other answers. I think either language will be fast enough for you. Clojure. Published at DZone with permission of Gary Sieling, DZone MVB. 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. Clojure wins because: Scala. One thing about Clojure is the language seems very simple. >> "than the performance " . Marketing Blog. 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). @javadba The idea that clojure is bad for low-level multithreaded code seems pretty arbitrary. -1 "both Scala and Clojure are JVM languages so they should have similar performance" makes absolutely no sense. Calling Java methods is straightforward, but extending Java classes/interfaces is quite different. Developer All you'll get is slow Java that's hard % ./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 … Four of the five top paying languages are the functional programming languages Clojure, F#, Scala and Elixir. Or, perhaps, more seamlessly. Join the DZone community and get the full member experience. How are you using Clojure? But then again, Scala has a very flexible type system. Should I hold back some ideas for after my PhD? First off, a language isn't inherently slower than another but "equivalent" programs may have different performance characteristics. Would coating a space ship in liquid nitrogen mask its thermal signature? Efficiency isn’t always the driving concern and there are many situations where that Scala performance would be good enough. Classes Vs Data. 15 replies Scala. A comparison of Clojure and Scala for implementing a web API. Scala is functional in the broadest sense of the word: It has immutable constructs. Is Java “pass-by-reference” or “pass-by-value”? 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. 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 … Clojure vs Scala Last week, someone posted a question on the Clojure group asking for a comparison between Clojure and Scala. The type system in Scala is Turing complete. You can implement an interface, extend a class, declare private and static functions, etc. Therefore, most data will be immutable by default. Has the Earth's wobble around the Earth-Moon barycenter ever been observed by a spacecraft? People asked about a few other languages as well, so let's get them out of the way first. Syntactically, it's also the furthest of the three languages from typical Java code. Clojure is a functional language in the LISP family, it's also dynamically typed. that Clojure can generate code very similar to statically typed languages using type hints. Why not try them both? State change is handled by functions (for transformations) and atoms (an abstraction that encapsulates the idea of some entity having an identity). Ni l’un ni l’autre ne se trouve bien en dessous. Syntactically, it's also the furthest of the three languages from typical Java code. Functional and sequence abstractions do not appear. 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. @Daniel: Sorry for confusion. Replacing a 32-bit loop counter with 64-bit introduces crazy performance deviations with _mm_popcnt_u64 on Intel CPUs. Clojure. > Rust is faster than Java, and Clojure can only ever match Java in performance, not exceed it. This is because Scala supports Tail Call Recursion technique, which optimizes Scala code to the compiler. 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. In my view, Scala is Java done right. I meant the comment towards Ryan Delucchi. Scala or Clojure Functional Programming best practices. A quick perusal of eFinancialCareers technology jobs confirms the results of this survey - there just aren’t that many roles for functional languages. 2.) He says that Scala is a "scripting language embedded in Java", which I don't buy. When comparing Python and Java, it seems a bit unreasonable to blame the language for the speed difference. Possibly, ordinary Scala is faster than ordinary Clojure, but you only need to optimize the bottlenecks. Benefits? But both Scala and Clojure are JVM languages so they should have similar performance. And the results are not encouraging. And since Scala author Martin Odersky wrote Sun's Java compiler, I kinda think no balls have been dropped on the Scala side, either. Mais ce n’est pas le cas, même si vous le pensez. site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. On interoperability, I can't speak for Clojure, but I would expect it to be in a similar situation as Scala. When I moved from Java to Python, I fell in love with Mutable Dictionaries. What to do? 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, and Scala. Scala classes may compile to a number of classes with names that look funny in Java. TL;DL; Intro; Goals; Building Web API. 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? Most of a … What's the word for someone who takes a conceited stance in stead of their bosses in order to appear important? multiply by hundreds of millions .. With Clojure, you compile down to Java Byte Code when you run your application or library. Clojure, Kotlin, and Scala are probably your best bets out of the 14 options considered. It can get work done even faster than Java. * dalvik (android's JVM) got a JIT compiler in 2.2 version in 2010. So, if Clojure is significantly slower: I'd like to know sooner rather than later. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Proof? You can go for Scala lite: writing Java idioms in Scala. Most of a … I learned scheme first, then haskell, then (now) clojure. To learn more, see our tips on writing great answers. These languages are at the very bottom of the popularity scale in the same survey. Scala is an object oriented language which has functional programming features. 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.
