I just built a new box with the AMD Phenom 9500 processor, gigabyte am2+

This thing rocks so hard for spamassassin, it's amazing.
Most of my other backend spamassassin/clamav/amavis boxes were x2 or
dual opteron singlecore systems with 2-3GB ram, not bad when I built
them or bought them. I ran 12 spamd processes at a time and cpu was
close to 100%.
I just unleashed a big queue of email onto the new and old servers, and
they are both working at full speed to catch up. It' got 24 spamd
processes going right now and is only running 40% cpu usage. Also in a
short period of time, it processed 700 emails, where the old server had
processed 300. It looks like I can run a lot more spamd processes than
24! I basically run as many processes as it takes to max out either the
CPU or memory of the server under a load. Looks like it has hugely more
capacity that I can tune for. Looks like this box may do the work of
three of those.
With the low prices of multicore CPUs these days and cheap ddr2 memory,
it's a great time to upgrade mail servers.
That's good to know. I've been using AMD 6000 X2 and 8 gigs of ram. I've
been interested in the quad cores but haven't felt that they were ripe
yet. Waiting for more AM2+ boards (with video on motherboard) and
perhaps DDR3 ram. (Or the new AM3 socket that's coming.
Thanks for the review.
