using as a benchmark compressing my cvsroot with
time tar cjf cvsroot.tar.bz2 cvsroot
on an Athlon 1400 (or 1600, dunno ...). Size of the dir is 5.3M.
Debian's debs:
around 3.6 seconds
compiled bzip2 and tar with DEBIAN_BUILDARCH=k6:
around 3.5 seconds
compiled with DEBIAN_BUILDARCH=k6 and GCCVER=3.0
around 3.3 seconds
compiled with DEBIAN_BUILDARCH=athlon and GCCVER=3.0
around 3.3 seconds
(note: arch=athlon doesn't work for gcc2.95)
