lolbench: automagically and empirically discovering Rust performance regressions

2018-09-29 | performance

lolbench compiles ~350 benchmarks with every Rust nightly. It then runs them and highlights potential performance regressions in the standard library and the output of the compiler. Each toolchain's run is summarized with a list of likely candidates, as seen in the image below, and we're now getting started using these to safeguard the performance of Rust programs. Come help!

Measuring Rust Runtime Performance: cargo bench vs. getrusage()

2016-02-24 | performance

Comparing cargo bench results to a slightly more robust method eliminates a lot of the noise, but there still appear to be a few performance regressions that both methods agree on. If someone has the statistics expertise to set me straight or help me take this further or both, please get in touch.
