jmh-gradle-example's Introduction

Example using JMH with Gradle

An example project that uses JMH with Gradle, but without melix/jmh-gradle-plugin.

Usage

First, build a shadowJar of the project and benchmarks:

./gradlew clean :benchmark:shadowJar

Then run the benchmarks:

java -jar benchmarks/build/libs/benchmarks.jar

Running this on Oracle Java 1.8.0 u251:

Benchmark                    (size)  Mode  Cnt      Score      Error  Units
