I did this on two machines: an old dog, and a new burner. System 1: HP 9000 Model H50 (PA-7100, 96 Mhz), 256 MB RAM, HP-UX 10.20

$ perl -v

This is perl, version 5.005_03 built for PA-RISC1.1

results: Benchmark: timing 1000000 iterations of Grep, Max, Ternary...
      Grep: 26 wallclock secs (21.98 usr +  0.17 sys = 22.15 CPU)
       Max: 33 wallclock secs (31.87 usr +  0.07 sys = 31.94 CPU)
   Ternary: 35 wallclock secs (33.29 usr +  0.13 sys = 33.42 CPU)
