You should definately look into Benchmark. I was able to reduce your test down to this, and I get the CPU usage
'unpack' => 'unpack "H*", "abc"',
'sprintf' => 'sprintf "%x%x%x",ord("a"),ord("b"),ord("c
Benchmark: timing 1500000 iterations of sprintf, unpack...
sprintf: 0 wallclock secs ( 0.17 usr + 0.00 sys = 0.17 CPU) @ 88
(warning: too few iterations for a reliable count)
unpack: 10 wallclock secs ( 9.87 usr + 0.01 sys = 9.88 CPU) @ 15
ACCCK!!!Abigail-II caught me in a latenight brain seizure. I shoulda been tipped off by sprintf winning. :( ++Abigail-II
