. The Scala compiler, known as scalac (remember javac) does more than you expect. make # e.g … Readability : Scala is less readable because of its nested code. Lift Framework example source code file (Benchmark.scala) This example Lift Framework source code file (Benchmark.scala) is included in the DevDaily.com "Java Source Code Warehouse" project.The intent of this project is to help you "Learn Java by Example" TM. Scala code is more clear and concise. Benchmark.scala Controller that runs benchmarks PersistableApp.scala ... Below is a Scala code snippet showing how instances of the some standard Java threadpools are configured. At QuantumBlack, we often deal with multiple terabytes of … 2.7. Iterating over 1000 elements of the given collection. I just wanted to iterate the collection but I need to do something with the elements or the JIT will drop the dead code. Refer to their step-by-step guide on the Kiuwan website. Activity. You can navigate to HotBloopBenchmark to have a look at the source code of the benchmark. Google's benchmark did not test concurrency, an area of particular focus for both Scala and Go. Introduction. Another contribution is the subsequent analysis of this suite and an in-depth, VM-independent comparison with the DaCapo 9.12 ... 6.3 The Effect of Scala Code on Just-in-Time Compilers. Instantly share code, notes, and snippets. I recently tested the benchmarks of Scala and Java on my AMD-A8 CPU. Operators are treated differently and is not done using the call method. reactions. An execution of the benchmark toolset across the suite of test implementations, either in full or in part, in order to capture results for any purpose. The run method embodies the microbenchmark code which will be run repetitively and whose running time will be measured. Micro Focus (Formerly HP) Fortify. Java is more readable. Use case: akka/akka Run benchmarks for bloop. Computer Language Benchmarks Game: Speed test java/scala 1.71/2.25. This should build the Scala package as well as the maven project of Scala benchmark. . Also, to print code generated by the eval macro use the -Dmacro.settings=print-expr-results option.. In the following graph, all execution times are normalized against the hand-written JavaScript code, instead of the JVM. If you are using the Audit Workbench, you can give it more memory and make sure you invoke it in 64-bit mode by doing this: Compute.scala vs ND4J on an NVIDIA Titan X GPU (source code) Compute.scala on an AMD RX480 GPU (source code) Some information can be found in the benchmark result: Apparently, Compute.scala supports both NVIDIA GPU and AMD GPU, while ND4J does not support AMD GPU. I’ve revisited the benchmark I used in 2012 and incorporated AnyRefMap, benchmarking it alongside java.util.HashMap and collection.mutable.HashMap. round A posting of "official" results on this web site. Google has published a paper (PDF) comparing performance of four programming languages, C++, its own language Go, Java and Scala. therefore the design of a Scala benchmark suite that is on par with modern, widely-accepted Java benchmark suites. The result I got was actually unexpected. So, this benchmarks say that java is 24% faster and scala uses 21% more memory. This will run the benchmark 5 times, forcing a garbage collection between runs, and printing the execution times to stdout. All code in the benchmark should be compiled and generated as Jar files. Memory test java/scala 66.55/80.81. It can generate toString(), equals(), hasCode() and other things for you. Created Apr 10, 2013 Kiuwan Code Security. Luckily, JMH already takes care of many things, and has bindings for both Java and Scala. In Scala, all the operations on entities performed using method calls. However not all language APIs are created equal and in this post we'll look at the differences from both a syntax and performance Growing. Automated Code Reviews for Scala. Java and Scala compile to Java Byte Code, while C++ and Go compile to machine code. The focus of this blog post is on AnyRefMap, which is likely to see very widespread use in Scala codebases. .115 . The Scala Benchmark Suite is based on the latest release (9.12, nicknamed “Bach”) of the DaCapo benchmark suite, a suite already popular among JVM researchers which specifically strives for “ease of use.”The Scala Benchmark Suite adds 12 Scala benchmarks, summarized in the table below, to the 14 Java benchmarks of the DaCapo benchmark suite. It is also possible to add a multiplier, so > scala sort1 5 10. will run the entire benchmark 10 times, each time for 5 runs. Conclusion. Conclusion Lift Framework example source code file (Serbench.scala) This example Lift Framework source code file (Serbench.scala) is included in the DevDaily.com "Java Source Code Warehouse" project.The intent of this project is to help you "Learn Java by Example" TM. Go was designed to be a concurrent language that offers the speed of … All-in-all it's no big deal and should not matter in real world apps, … Run Script Step. . A team at Google created a “simple and compact” benchmark … One of Apache Spark’s selling points is the cross-language API that allows you to write Spark code in Scala, Java, Python, R or SQL (with others supported unofficially). . sam / Benchmark.scala. While many languages share some of Scala’s features, few share so many of them, making Scala unique in ease of development. This is the sample Java benchmark: Run the benchmark as follows: > scala sort1 5. . Both options can be combined: -Dmacro.settings=print-codecs,print-expr-results Run JVM benchmarks. Here is a short example: ... (1, 1000)) } The run method has to be defined by the user, who will perform the timed operation there. In order to to run Scala code via Graal, I created a toy example that is inspired by the benchmarks described above: The source code snippet below creates 10 million integers, increments each number by one, removes all odd elements and finally sums up all of the remaining even numbers. Though you can write compact codes in Scala, the performance i.e. . Kiuwan Code Security wrote their own instructions for scanning the OWASP Benchmark. As a Scala development company – we use Scala for a variety of reasons, which mostly come down to reducing development time and reducing the number of bugs in code. . Popularity. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. This blog will demonstrate a performance benchmark in Apache Spark between Scala UDF, PySpark UDF and PySpark Pandas UDF. @Benchmark public void init() { //code snippet } Inside this init method, we need to write code that needs to be executed repeatedly in order to warm up. The specialized collection offers very high performance for keys of type Long. scalajs-benchmark: Repository: 4,129 Stars: 62 241 Watchers: 9 646 Forks: 5 29 days Release Cycle: 148 days 3 months ago: Latest Version: 4 months ago: about 1 month ago Last Commit: 3 months ago More: Scala Language: Scala Compiler, Tools, Simplification Tags The object Map above extends the scala.testing.Benchmark trait and parses system specified parameters par for the parallelism level and length for the number of elements in the trie.. After compiling the program above, run it like this: Compute.scala is faster than ND4J when performing complex expressions. Scala benchmark is a little better because the generated code with closed method is a bit better than the one calling the recursive one. Compiling process : Compiling the process of source code into byte code is very slow. Compare scalajs-benchmark and Codacy's popularity and activity. But in this particular example, the difference is miniscule. Code was compiled with Scala version 2.9.0-1. 7. We ran our experiments in Sun’s Java SE Runtime Environment, build 1.7.0-b147, using the HotSpot 64-Bit Server VM with default options. preview A capture of data from a run used by project participants to sanity-check prior to an official round. In the last 20 years, most contributions to Java were related to the GC (Garbage Collector) and JIT (Just In Time Compiler). . For three benchmarks, we also have the hand-written JavaScript code, coming from the JavaScript Octane benchmark suite. Before benchmark running check if your CPU works in performance mode (not a powersave one). By the way, ... Scala has set a new benchmark in being concise and readable at the same time. Performance Benchmark . Scala Java; in … Benchmark code for algorithms in this Stack Overflow question regarding Java vs Scala performance: http://stackoverflow.com/q/7084212/53013 - BenchCode.scala the speed is actually twice times as slow when compared to Java. Please follow the procedures on JMH page to get the benchmark project, then you can transplant the benchmarks below there. I could have used Scala’s sum() helper function but I wanted to avoid any optimisations that it may introduce. . Here's a list of the steps to benchmark … Benchmark can be used to quickly turn an existing class into a benchmark. On Linux use following commands to print current and set the performance mode: In fact, when writing Scala code, you tend to use a lot of exactly the same libraries between Java and Scala, because to the JVM it's all just bytecode. Benchmarks marked with M use mutable collections Tons of effects need to be mitigated, including warmup, dead code elimination, forking, etc. We compare Scala.js’ production mode against the hand-written JavaScript code below. The following examples show how to use scala.tools.reflect.ToolBox.These examples are extracted from open source projects.
