Hardware for INN

Hello all,

I am curious about something.  Is anyone out there running INN successfully
on a FreeBSD/Intel box?  I'm running one of the snapshots from June 1999,
and my system is unable to keep up with a full newsfeed at today's levels.

Here's a quick rundown of my setup:

Hardware is PIII-800 single processor with 512M of RAM.  It has 12 drives,
36 and 50 gigs, not raided.  Storage method is cycbuff, with the overview
being written in the 2 files/group format (Sorry, I don't remember the name
for this, but it's the one that creates the .IDX and .DAT files for each
group).  The max I've been able to get this system to accept is about 130
gigs a day.  All drives are LVD seagate barracudas.

In contrast, I have another backbone-only system that is almost identical in
configuration.  It only has 3 drives, and the overview is disabled.  It's
been able to keep up with up to 190 gigs/day of traffic.

I'm thinking that the problem lies, at least partially, with the overview.
Here is a copy of today's INND timer stats:

My biggest question is whether or not anyone is successfully running INN
with a full incoming news feed (at least 170 gigs/day) on a setup similar
to mine.  Or am I missing some huge problem here.

Thanks.
