I have a Virtual machine running on an old -- and I mean old (Quad Intel Pentium 4 Xeon) server. My load average is bad on the VM, the physical machine looks ok. The physical machine is slated to be replaced, but not for approx 90days. It's causing duplicate emails to come in to users accounts. Spamdyke is helping a lot. I have killed RBLS in qmail and Spamassassin, no sense in checking them twice. I have disabled autolearn and am not using the Bayes database in Spamassassin. I am trying to optimize simscan, since I see scan times that are pretty bad -- the first one I looked at was 25 seconds. I turned off clam by editing simcontrol to :clam=no. I am trying to think of any other things I can do to help out this server in the interim. I found a script that says it does the following things that make a lot of sense to me:
I'm curious what your load metrics are. I've worked on 5-6 virtual QMTs in the last couple weeks, and everything seems to fall down around the 500 user mark (or equivalent load). This has been on ESX, Xen, and ESXi. We had some discussion on this on the devel list, since this is a little concerning. I have bare metal machines that have 2200+ users that run without any problem, and on "low-end" hardware (P4 2.4Ghz, 2G RAM). Also curious to see if you get the duplicates in webmail as well as lookOut. I suspect you get them in lookOut but do not see them in webmail.... If that's the case you can toss out any ideas that spam/virus/simscan are causing your problems.
