I run my SMTP server entirely in a VMware VM, and have *never* seen a high CPU usage on that particular machine. I run Postfix, Amavis-new 2.4.3, SA 3.1.7 and quite some plug-ins.
Bayes and quarantine are all in a MySQL database stored on another VM, no big load there either... At peaks, I have a 2-4% CPU usage and 20-65% memory usage on eash VM, all reported by Virtual Center 1.4.
So, naturally I'm curious about why there would be a high CPU load from using SA.... My guess is that it's something else causing it.

I'm pretty sure it is that, because when I turn of bayes altogether, the spikes go away. I also ran sa-learn --force-expire and it PEGS the VM. With bayes debugging enabled, I see lines like this in my syslog:bayes: expired old bayes database entries in 236 seconds: 152268 entries kept, 9457 deletedWe have about 140 users, each with a 5 MB bayes_toks file, so there is a need to expire somebody all throughout the day. Each user is virtual, they don't really have an account on the box, but the directories correspond to each user address. And we do auto-learn, with opportunistic expiry.Good thought about --round-robin, I am willing to use a little more memory if it saves on CPU.*/"Ring, John C" <[EMAIL PROTECTED]>/* wrote: >From: Sammy Anderson [mailto:[EMAIL PROTECTED] > >We recently migrated our SpamAssassin installation from a physical 3.6 GHz system >running RHEL 4 and SA 3.0.4 to a VMware VM (ESX 2.5.4) with RHEL 4 as the guest OS >and SA 3.1.7.

We're using ours as a site-wide MTA to be able to reject incoming mails at SMTP time, so no user DBs on the box, but we are running with Bayes checking on (Berkeley DB), autolearning off, and manual Bayes feeding only a few times a day. Because of that, I don't have practice with a heavy Bayes load, but how certain are you that it's Bayes hitting the CPU; did you run sa-learn (or spamassassin) with network reporting turned off to see if that makes a difference? I ask because pyzor did keep our CPU at a constant 75% until I turned it off; now it varies from 25% to 75% over the day, which is a lot more acceptable :) Another thought, albeit perhaps not directly related, is are you running spamd with --robin-robin? When I did that, it reduced the CPU load with the trade-off of using a little more memory, which seems to be the better trade-off, especially for a VM on ESX.-- John C.
