I don't fully understand what you explained above. Could you explain more?
Having a bunch of unused processes hanging around could make it less likely to hit a process that is pre-loaded in the processor cache, and more likely to hit a process that has been swapped to disk-based mem cache. The first issue should be relatively minor, but the second could be quite major if you don't have enough physical ram.
