Nope doesn't seem to be.  The machine is sitting on 100% CPU, which is
why it is running really slow.  :-)  obviously.  But, there are no 'run
away' processes, the IMAP server is running on the same machine.  The
disk subsystem is not being pushed and is well within 'safe operating
levels'.  We are not swapping, we are using just over 1 of the 2 gigs of
RAM available.

We have been through the web server and the OS and performed the usual
optimisations (we have a few other highly active web servers).  The next
step is the application (IMP).  I am unsure if it will help too much
though.

Have you (or anyone) had much experience with php optimisers?

Yeah, well, when this little stint is over I have a real job to go back
to.  :-(
