Have you applied Jake's change for the simscan working directory?
No I haven't. But will look into

You don't need more ram. Your swap file is virtually unused, and there is 1.2G cached i/o. As your processes require more ram, linux will reduce the i/o cache to accommodate it. You have plenty of ram IMO.

As a side note, 4G of swap is overkill as you can see. Making swap 2x the amount of ram used to be the rule of thumb, but that's not as applicable these days with so much ram. In your system, I think I would use 1G of swap. If your system actually uses that much, performance will be suffering, and at that point you'll be wanting to add more ram.
OMG, I am an outdated sysadmin :(

So back to your performance issue. Your Cpu is not strained (96.4% idle), and not waiting a lot either (2.6%). That's good.

Your load is fairly high though, 1.0+ over the previous 15 minutes and trending upwards. This is puzzling to me. I've seen this sort of thing before, but only in a VM environment. This isn't a VM guest is it?
So CPU is not an issue here. Great. the QMT is on Dedicated Server

Do you have zombie processes running? Your cpu load is low, yet there are 3 spamd processes running.
I thought spamd has 2 standby child-processes and the other one is the master process

Anyone else have any thoughts about this (slightly) high load?


Thanks Eric for your detailed review regarding my system. The reason why I am asking this question because some users complaining sometimes they had double emails which sent to their email address not from milist. From reading the archive and previous question I ask to this milist, it was lack of memory problem. that's why I submit my memory usage along with qmt statistic.
