rperf2

Tool for latency-analysis in Java

How it works

There are two modes for rperf2:

1. Classic mode: just skip N invocaitons and profile N+1 invocation
2. Quantile analysis mode: you specify required percentile, after that profiler will wait for appropriate case of slowing down and outputs TOP and trace

How to build

1. Download with modules git clone --recursive REPO_URL_YOU_USE
2. Build profiler make build-libipt (may require some environment variables to be set)
3. Build instrumenter agent make build-instrumenter
4. Use it! See examples at Makefile
