Hmm, a 200 MHz Pentium (MMX), 3.2-RELEASE, everything in cache:
$ /usr/bin/time file twofish.tar.gz
twofish.tar.gz: gzip compressed data, deflated, last modified: Mon Jun 15
02:40:53 1998, os: Unix
0.35 real 0.24 user 0.10 sys
I'd say that considering that things are cached (cpu-bound), it's very
accurately proportional to Leif's time. Variances can be accounted
for by the slight implementation differences (the MMX version has a
bigger L1 and better branch prediction).
It's also reasonably proportional to a 400 MHz PII (0.09/0.08/0.01
running 3.2 -- 0.06/0.04/0.01 running 2.2.8, BTW). Considering the
completely different core, this is also quite close to what you might
expect.

What are your results, then?
