Documentation on writing and running benchmarks is included as part of the standard documentation..The benchmarks are included as part of the project that is being benchmarked.In Go, benchmarks are run with the command go test -bench=…The ..is a regular expression for the name of the benchmark functions you want to run; a dot means to run everything..There are additional flags as well that control other aspects of benchmarking, like whether to benchmark memory in addition to performance, or how long to run the benchmarks..And, as we’ll discuss in a bit, this integration with the standard distribution has other implications as well.Java’s approach is different..The standard Java benchmarking library is JMH..Even though it is written and maintained by Oracle, it isn’t bundled with the standard library..The recommended way to use JMH is to create a separate benchmarking project..Developers then use maven (the popular third-party project management tool) to run this not-so-simple command:mvn archetype:generate -DinteractiveMode=false -DarchetypeGroupId=org.openjdk.jmh -DarchetypeArtifactId=jmh-java-benchmark-archetype -DgroupId=org.sample -DartifactId=test -Dversion=1.0When it’s time to run your JMH benchmarks, the standard way is to use the commands mvn clean install; java -jar target/benchmarks.jar..This builds and runs the benchmarks in your benchmark project..There are options, lots of them..
