Warming up --------------------------------------
               block     1.000  i/100ms
              ensure     1.000  i/100ms
Calculating -------------------------------------
               block      1.099  (± 0.0%) i/s -      6.000  in   5.460202s
              ensure      1.400  (± 0.0%) i/s -      8.000  in   5.713243s

Comparison:
              ensure:        1.4 i/s
               block:        1.1 i/s - 1.27x  slower
