timer

This project is archived. Use hyperfine instead.

timer is like time but repeats your command and provides basic statistics on execution time.

It's inspired by perf stat, but works on macOS.

Install

go install github.com/coder/timer@master

Parallelism

You can use the -p flag to configure the number of parallel threads.

$ timer -n 4 -p 2 sleep 1
--- config
command        sleep 1
iterations     4
parallelism    2
unit           1s
--- histogram
1.012-1.014  50%  ████████████████▏  2
1.014-1.016  25%  ████████▏          1
1.016-1.018  0%   ▏                  
1.018-1.020  25%  ████████▏          1
--- summary
total     2s
mean      1.015
median    1.014
stddev    0.004
