Add JMH Benchmarking

Overview

This PR introduces a dedicated JMH benchmarking module (benchmark-jmh) to provide basic microbenchmarking for performance measurements for jvector operations. The module enables systematic performance testing and comparison of variants of the vector search such as:

  • Search OnHeap/OnDisk
  • Random datasets vs static datasets.
  • Search latency increase with dataset size
  • Compare different scorer implementations

Changes

  • Add new benchmark-jmh module
  • Implement two sample JMH benchmarks for basic tests RandomVectorsBenchmark and StaticSetVectorsBenchmark
  • Add logging configuration for benchmark execution
  • Include benchmark documentation and usage instructions

Implementation Details

  • Uses JMH 1.37 for microbenchmarking with blackhole compiler settings
  • Includes both throughput and average time measurements
  • Implements proper warmup and measurement cycles

Usage

mvn clean install
java --enable-native-access=ALL-UNNAMED \
  --add-modules=jdk.incubator.vector \
  -XX:+HeapDumpOnOutOfMemoryError \
  -Xmx14G -Djvector.experimental.enable_native_vectorization=true \
  -jar benchmarks-jmh/target/benchmarks-jmh-4.0.0-beta.2-SNAPSHOT.jar

Output

The output summary will look like this:

The full output will look something like this:

REMEMBER: The numbers below are just data. To gain reusable insights, you need to follow up on
why the numbers are the way they are. Use profilers (see -prof, -lprof), design factorial
experiments, perform baseline and negative tests that provide experimental control, make sure
the benchmarking environment is safe on JVM/OS/HW level, ask for reviews from the domain experts.
Do not assume the numbers tell you what you want them to tell.

NOTE: Current JVM experimentally supports Compiler Blackholes, and they are in use. Please exercise
extra caution when trusting the results, look into the generated code to check the benchmark still
works, and factor in a small probability of new VM bugs. Additionally, while comparisons between
different JVMs are already problematic, the performance difference caused by different Blackhole
modes can be very significant. Please make sure you use the consistent Blackhole mode for comparisons.
