Run hyperfine 'cmd1' 'cmd2' to time both commands and print a comparison.

01Command

Command
$ hyperfine 'sleep 0.1' 'sleep 0.2'

02What it does

hyperfine runs each command multiple times, discards warmup runs and reports mean, min, max and standard deviation with outlier detection. Use --warmup, --runs or --prepare to control the measurement, which makes it far more reliable than watching time output once.
