Caught my name there. :) I'm actually doing it, though the machine does
not get too many hits. This is a T1-connected mirror server in the US which
we use to serve up hits to our local sites, speeding up our perceived
WWW speed, when working in conjunction with a "redirector" script under
Apache which just gives the browsers a Location: header.

Look at the process start dates; in fact, they're still doing Squid 1.0.2.
RunAccelOne is a script that runs a single accelerator, taking care of
putting logs. Consolidating all these processes into a single one
would be nice though. Eliminating the useless ftpget would be easier,
but since it isn't a problem at this site, I haven't taken the trouble yet.

This is a FreeBSD 2.1.5 system, P150, 32 MB RAM:
