bench

Overview ¶

Benchmark tool to compare performance between multiple compression implementations. Individual implementations are referred to as codecs.

Example usage:

$ go build
$ ./bench \
	-formats fl              \
	-tests   encRate,decRate \
	-codecs  std,ds,cgo      \
	-globs   twain.txt       \
	-levels  1,6,9           \
	-sizes   1e4,1e5,1e6
