nimble install benchy
This library has no dependencies other than the Nim standard libarary.
Simple benchmarking to time your code. Just put your code in a timeIt block. Also put result of your computation into keep() so that compiler does not optimize it out. Don't forgot to run with -d:release or better yet -d:danger.
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
keep(s)
timeIt "string append":
var s = "?"
for i in 0 .. 26:
s.add(s)
keep(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.
