A complete benchmark tool (and suite) for Ruby implementations and libraries

by Benoit Daloze for JRuby

This project is to develop a benchmark tool which allows to compare implementations, with different flags and over time in order to keep track of performance (avoid regression) and detect where it could likely be improved. It also includes creating a coherent and high quality benchmark suite starting from existing ones. In particular it would allow to accurately measure JRuby performance by differentiating early/long-term performance, and the effect of invokedynamic and other external factors.
