For example:

▶ hyperfine "echo 1" "echo 2" --runs 10

Benchmark #1: echo 1
  Time (mean ± σ):       0.0 ms ±   0.0 ms    [User: 0.0 ms, System: 0.3 ms]
  Range (min … max):     0.0 ms …   0.0 ms    10 runs
 
  Warning: Command took less than 5 ms to complete. Results might be inaccurate.
 
Benchmark #2: echo 2
  Time (mean ± σ):       1.8 ms ±   1.2 ms    [User: 2.0 ms, System: 0.7 ms]
  Range (min … max):     0.0 ms …   4.3 ms    10 runs
 
  Warning: Command took less than 5 ms to complete. Results might be inaccurate.
 
Summary
  'echo 1' ran
     inf ± NaN times faster than 'echo 2'
