It seemed a bit odd to me, but what do I know? ;-)

I'm using kernel 2.2.17+ReiserFS+latest IDE patchset, and glibc-2.1.3.
Pretty much stock Red Hat 6.2 with all errata, and a custom kernel RPM.
  It's the same kernel and glibc we ship with, so it's proven pretty stable.

fragmentation, by any chance? ;-)

I'll run some more benches right now with the newest squid-HEAD and see
what comes of it.
