I have an Ubuntu Linux server running SpamAssassin Server version 3.2.4 running on Perl 5.8.8 with zlib support (Compress::Zlib 2.008). I have at least one account that is having to process from 250 - 400 emails, 99% spam, per HOUR. This works out to be approximately 8,000 emails per day. The spamassassin just can't keep up and it is backing the Queue upto 2500 messages. I have made an adjustment so that the one user can have multiple spamd children running for it, but it doesn't seem to take on more that 2 spamd children.
I have also recorded that scanning a single message appears to take approximately 15 seconds. I have adjusted the timeout to 5 seconds, but it still appears to be taking 12 - 20 second per message. This works out to 4 per minute, or 240 per hour. So, of course, it can't keep up if it has 450 per hour coming at it. The system is a basic Linode running Ubuntu Linux 8.04 with 512M of memory. I would like to adjust appropriately Number of Max Children Number of Spare Children Number of spamd services per account (upto max children if possible) TimeOut on Scanning of the eMail Suggestions will be appreciated. Thank You Russ
