Yeah, I got the SMP option built into the kernel and still with less than 700 messages in the queue, very little else going on beside Postfix with amavis content filtering, my CPU idle is 0% most the time. This is on my freshly built FreeBSD 5.4 with dual Xeon 2.4 processors and a GB RAM. You think that could be related to HT? I will have to make a visit to the data center to remove in BIOS.
