JMH is the Java Microbenchmark Harness, a tool for building, running, and analysing nano/micro/milli/macro benchmarks on the JVM. It generates synthetic benchmark code via annotation or bytecode processors to produce reliable performance measurements.
Use cases
- benchmark java methods at nanosecond precision
- measure jvm code performance reliably
- compare performance of alternative implementations
- run microbenchmarks from maven project
- benchmark scala or kotlin code on the jvm
- avoid jvm jit benchmarking pitfalls
When to choose
- you need statistically rigorous JVM microbenchmarks
- you want the de facto standard Java benchmarking harness maintained by OpenJDK
When to avoid
- you need application-level load testing rather than code microbenchmarks
- you are benchmarking non-JVM languages like Python or Go
