on the Processes tab right click the process(s) you want and select to set affinity. MOST will allow you to do so but a few will not so those few you ignore.
You can also set priority for processes. I would suggest that you record what the original settings are for each before making any changes.
I have a dual processor, but my response time is still slow. I have 2 Xeon 2.4 ghz with 1Gb 333 of RAM. Are there any Cmos settings or any way to have certain applications look at the 2nd processor so that one processor isnt bogged down before my 2nd one is even used? I know there are alot of little side tricks to use so any thing would help.
