Just a little follow-up to my own post.

From the latest expriments I've done with a fresh install of OS X 10.4 (with
the latest 10.4.3 beta update), it seems to point to an IO problem.

My test site uses mambo as a CMS, and I've inclued collecting of
microseconds timestamps at key points of the index file, and whenever it
includes some files it slows down. It's worse when there are several nested
includes. One other point is the mysql db connection.

I must recall to all that when called from the cli, it's ok. Only when
called from apache (1 or 2), dso or static and only on Mac OS X 10.4 (it's
ok with 10.3 and 10.2) I expericed a major slowdown. For all tests, all
config is the same, libraries and binaries where all the same on all
systems.

I've tried compiling php as cgi also, it helps a little bit, but it's still
too slow...

Thanks for any hints...

Nicolas
