[imp] Tuning IMP for performances

Just various past mailing list postings.  Also, look at various general
performance web sites like linux/solaris/whatever tuning, apache tuning,
php tuning, etc.

Often is.

It mostly effects file uploads, so I set it based on that and RAM available.

Yes.   But unless you have a very small memory machine, it should never be
so large as to induce swapping.  If it is, then something is out of whack.

I just today, in response to your message, created a horde/docs/PERFORMANCE
file for performance tips.  Right now, there isn't much in it.   But hopefully
it will grow to contain more info.
