BenchPress

BenchPress is a library used to run micro-benchmarks on Haskell code. It produces detailed reports of the run benchmark that can be used to better understand the behavior of the function under test.

Here's some example output:

$ ./my-benchmark Times (ms) min mean +/-sd median max 197.840 321.024 134.126 272.296 603.299

Percentiles (ms) 50% 266.748 66% 292.810 75% 293.004 80% 293.004 90% 532.179 95% 603.299 98% 603.299 99% 603.299 100% 603.299

INSTALLING

BenchPress uses the Cabal build infrastructure for building and installing. If you have cabal-install installed it is as simple as:

$ cabal install benchpress
