About

Simple benchmarking to time your code. Just put your code in a timeIt block. Don't forgot to run with -d:release.

import benchy, std/os, std/random

timeIt "sleep 1ms":
  sleep(1)

timeIt "sleep 200ms":
  sleep(200)

timeIt "sleep random":
  sleep(rand(0 .. 150))

timeIt "number counter":
  var s = 0
  for i in 0 .. 1_000_000:
    s += s

timeIt "string append":
  var s = "?"
  for i in 0 .. 26:
    s.add(s)

It will run the timeIt block at least 10 times but possibly more to figure out the standard deviation. It will keep running it until things look like they stabilized. It will stop after 60s though.
