JMH is an SBT plugin for running OpenJDK JMH benchmarks. Per its docs, “JMH is a Java harness for building, running, and analysing nano/micro/milli/macro benchmarks written in Java and other languages targeting the JVM.”
They also recommend reading an article titled Nanotrusting the Nanotime if you’re interested in writing your own benchmark tests.
