run microbenchmarks locally

• install async profiler, https://github.com/async-profiler/async-profiler/releases/tag/v3.0, use binary for your target CPU architecture
• install hsdis (https://chriswhocodes.com/hsdis/) into your $JAVA_HOME/lib/server/, use binary for your target CPU architecture
• LINUX ONLY: configure your system with sysctl kernel.perf_event_paranoid=1 and sysctl kernel.kptr_restrict=0
• install JDK 21

run microbenchmarks with docker

Build docker image:

cd src/main/docker
docker build . -t microbenchmarks

And run benchmarks with:

./mvnw clean package
docker run --privileged --rm -v $PWD/target:/work microbenchmarks java -jar /work/benchmarks.jar -prof "async:output=flamegraph;dir=/work"

Without docker, you can run benchmarks directly on your machine with:

LD_LIBRARY_PATH=/home/jarek/tools/async-profiler/lib/ java -jar target/benchmarks.jar -prof "async:output=flamegraph"
