Awesome

A bundle of benchmarks measuring the performance of various fiber (lightweight thread, actor, coroutine, etc.) implementations for the JVM.

Benchmarks

Ring: N spawned threads are connected in a ring structure. Through this ring a message (an integer) is circulated M times. (Adopted from the Performance Measurements of Threads in Java and Processes in Erlang article.)

Implementations

Usage

You first need to build the necessary JMH fat JARs and then let the benchmark script do its job:

$ ./mvnw package
$ ./benchmark/benchmark.py

If you don't have a local JDK 11 installation, you can also use the shipped docker.sh to compile and run the benchmark in a Docker container:

$ ./docker.sh mvn-package
$ ./docker.sh benchmark

Results

For Oracle Java 1.8.0_121-b13 running on Intel(R) Core(TM) i3-2105 CPU @ 3.10GHz on Linux 4.4.0-137-generic x86_64 kernel:
