What are the best practices for using JMH in my Java projects?
The best practices for using JMH include setting up proper benchmarks, using warm-up iterations, and avoiding dead code.
Can you explain why warm-up iterations are important?
Warm-up iterations help to stabilize the JVM and ensure that the benchmarks reflect the performance of the code under normal conditions.
How do I set up a benchmark in JMH?
To set up a benchmark in JMH, you need to create a Java class annotated with @Benchmark
, and then run it using the JMH command line.
Are there any common mistakes to avoid when using JMH?
Yes, common mistakes include not using enough warm-up iterations, measuring too small code segments, and not isolating the benchmarked code.
