I would contend that this degradation in performance is a bug, and would
be a bug fix, not a feature.
I did mention this should probably be done (profile/optimize/tune) some
weeks ago.

If performance has been cut in half from 1.1.1 to 1.2, then it is a
showstopper problem. We should hold everything and concentrate all efforts
on evaluating performance issues.
I will try to do some performance testing this weekend.

Hmm, are these pages being served SSI's? Remember that we did notice that our
new SSI code is a fair bit slower and could be optimized.
mmap() instead of fopen(), anyone?
