An unspecified program:

FWIW, I have been using a self-compiled egcs using i686 as target for my own
use and a CPU-intensive program showed an increase of 50% in speed. It runs a
simulation and produces almost no output until the end so it's probably not
a good benchmark for packages. Still, it seems to make enough of a difference.

I've been using egcc for building, it's in debian. See another message I
posted today that explains how you can install the pentium optimized
packages I've built that are now on www.debian.org.
I only did 2 benchmarks myself. I timed multiple runs of gzip -9 and gunzip
on a large apache logfile, using first non-optimized and then the optimized
gzip and took the quickest from each set of runs. I got 10 to 15% speedup
there.
I also built xaos compiled for pentium and ran it with the option to
display the frames per second turned on, and had it display an introduction
to fracals tutorial that's in xaos. I saw more frames per second in the
pentium optimized version, I think about 10% more.
I also tried having bc calculate 10 thousand digets of pi, but saw no
speedup there. I plan to try that again with a pentium optimized libc6, in
case libc6 does all the math work in bc.
Not the best benchmarks, I just did those to justify to myself that this was
worth looking at. I'd appreciate more formal and better done ones.
