So I got around to benchmarking today. I was struck by the large variability in the benchmarks--2 orders of magnitude difference. So can someone explain why tadman's and MeowChow's subs are so much faster?

tadman original: timethis 100000: 70 wallclock secs (70.00 usr + 0.02 sys = 70.02 CPU) @ 1428.16/s (n=100000)
MeowChow: timethis 100000: 13 wallclock secs (12.25 usr + 0.00 sys = 12.25 CPU) @ 8163.27/s (n=100000)
no_slogan: timethis 100000: 81 wallclock secs (78.22 usr + 0.04 sys = 78.26 CPU) @ 1277.79/s (n=100000)
srawls: timethis 100000: 56 wallclock secs (53.80 usr + 0.07 sys = 53.87 CPU) @ 1856.32/s (n=100000)
tachyon: timethis 100000: 90 wallclock secs (89.07 usr + 0.06 sys = 89.13 CPU) @ 1121.96/s (n=100000)
tadman golf: timethis 100000: 1 wallclock secs ( 0.83 usr + 0.00 sys = 0.83 CPU) @ 120481.93/s (n=100000)

Experimental method:

I placed each sub in a holder script and executed it. The script looked like this: 

#!/usr/bin/perl

use Benchmark;
my $iter=100000;

while (<DATA>){ #tadman original

 timethis($iter, sub {

$_=pop;y/UCAG/0123/;s/(.)(.)(.)/substr
"FFLLSSSSYY..CC.WLLLLPPPPHHQQRRRRIIIMTTTTNNKKSSRRVVVVAAAADDEEGGGG"
,$1<<4|$2<<2|$3,1/ge;y/0123//d;$_

  });


}

__DATA__
yada yada... the CFTR mRNA from above.
