For reference, my clients usually take 0.3-1.5% CPU usage.
Code: Select all
Take this with a big grain of salt because I never tested the effects, but my client currently uses these settings (Underfoot) for CPUAffinity:
CPUAffinity0=7
CPUAffinity1=1
CPUAffinity2=2
CPUAffinity3=3
CPUAffinity4=4
CPUAffinity5=5
CPUAffinity6=6
CPUAffinity7=7
CPUAffinity8=1
CPUAffinity9=2
CPUAffinity10=3
CPUAffinity11=4
CPUAffinity12=5
CPUAffinity13=6
CPUAffinity14=7
CPUAffinity15=1
CPUAffinity16=2
CPUAffinity17=3
CPUAffinity18=4
Here's what I think it does...
CPUAffinityX=Y tells client number X to use core number Y. My understanding is that Y refers to a numbered logical processor on hyperthreaded machines. That means your dual core CPU has 4 logical processors and your quad core CPU has 8 logical processors.
Supposedly CPUAffinity and logical processor counting starts at zero.
If you have 3 clients running, then CPUAffinity1, CPUAffinity2, and CPUAffinity3 will be used.
If you have a dual core, hyperthreaded machine, then yours might look something like this for 6 clients:
CPUAffinity0=1
CPUAffinity1=2
CPUAffinity2=3
CPUAffinity3=1
CPUAffinity4=2
CPUAffinity5=3
What I did with my CPUAffinity settings above is deliberate. I have a quad core CPU with 8 logical processors. My settings can account for 18 clients. I left logical processor 0 unused, because my understanding is that it is most often used for system and various other processes. After skipping 0, I then re-use 1-7 over and over, spreading the clients out as evenly as possible.
Does it work? Don't know, didn't test it. But I can say that my i7 3770s (far from the best i7 around) doesn't break a sweat. 18 idle EQ clients and Windows 8, chrome, music, and various other things still hover below 15% CPU utilization. But, I play with graphic settings pretty low and mq2fps to manage well... fps :).
Feel free to try out my CPUAffinity settings and see if you can get any improvement. Of course, adapt it to the number of logical processors you have where fit. I'm curious what your results will be.
