We run SA 2.55, qmail-mail scanner (with F-Secure) and vpopmail on a 2.4Ghz P4 Dell Server with 1GB RAM and 120GB 10K ATA drive. Last week the server virus/spam filtered and popped 423,325 messages. During the last 2.5 days the server's handled 376,168 messages. The machine is smoken - looks like spam really picked up this week - the load average is running between 15.0 and 20.0 and CPU is almost 100% utilized. We'll be off-loading virus scanning to another server which should allow us to double or triple the throughput with SA. We've disabled some of the RBL's, DC and Pyzor - don't use Bayes either. But everyone's happy - we capture 97% of the spam. Law of diminishing returns - reducing the remaining spam by 50% would require double the equipment and personnel resources.

We run SA 2.6.1 on 4 identical machines. Each is an Athlon 2600, 1GB ram, 3com nic, seagate 80 GB 8MB cache cuda ATA100 drive. The 4th machine isn't slower, it just got less email sent to it.
Friday, they processed: 170140, 147646, 133958, and 63909 messages.
Got this by the command zcat /var/log/mail-20040109.gz |grep spamd |grep seconds |wc -l
Each machine has backhair, chickenpox, no-osiru, popcorn, and weeds_2 configurations. local config skips rbl checks and has the recent rules for strings of 10+ random words. We use postfix/SA/procmail/qpopper on Suse9.0. We use local files for user prefs.

That'd be great!
