Benchmark: running Step 1, Step 2, Step 3 for at least 10 CPU seconds...
  Step 1: 10 wallclock secs (10.17 usr +  0.00 sys = 10.17 CPU) @  5.11/s (n=52)
  Step 2: 10 wallclock secs (10.00 usr +  0.00 sys = 10.00 CPU) @  5.10/s (n=51)
  Step 3: 11 wallclock secs (10.72 usr +  0.00 sys = 10.72 CPU) @  0.47/s (n=5)
