What do you mean by "Don't forget to up your cache size as well." - the L2
cache is fixed !!! Or do you mean the cache of WU's to be processed?

Your WU cache... You'll be processing more WUs per day with four s@h processes running in (psuedo) parallel.

You get the extra WU throughput because you utilise the CPU cache better. The CPU gets a better chance to stay busy while waiting for the impossibly slow main memory to catch up.

I have a second PC, (dual P3/800MHz) - do I tick the box for "set affinity"
or leave it blank?
What does "set affinity" do?

Set affinity tries to keep a process with the same processor, and hence with its data that is already in that CPU's cache. This is a good idea for performance.
