All the sites on this box are static html sites.. very basic pages..
Active monitor only sends me the occational email that a user has gone
over their quota.. a couple of times it's sent me an email to say 'disk
useage is normal' but didn't state there was an error beforehand.

A couple of times it seemed swatch was the culprit, all that showed in
messages and security was something about another swatch proccess is
already running .... lockfile in '/var/lock' - I just removed the lockfile
and all came good. Other than that we haven't yet determined what's doing
this, the company I work for has had it for about 9 months and it's never
been _good_. It's been rebuilt twice in the 5 months i've been here.

I thought as much.. what about it not, or very rarely using it's buffers?

Is there any way to better benchmark this thing?

Thanks,
