So I ran through the guide here:
http://isboxer.com/wiki/HOWTO:Tweak_...te_bottlenecks

And I noticed that only two of my 4 CPU's are not being used much, like CPU 1 &2 at 90% while the others are under 10%. I was running 5 toons with Round robin CPU 1 dedicated and I was chugging like crazy.

Memory was maxed out too, I knew 8GB wasn't going to be enough.

Any thoughts?
