I know in WIN XP Pro you can assign tasks to run on specific cores. My question is 2 parts ...

1) Is there any real benefit to actually doing this? Say assigning AV,Firewall software to specifically run on CORE 2 (aka 1 in a 0 + 1 assignment)?

2) If I assign stuff to run on a certain core will it remember which core to run on at the next start up?

Thanks

To assign tasks to run of specific cores, open the task manager, find the process you want to assign, right click it and select "set affinity."

There really isn't much benefit to changing a process's affinity. The only time I have ever done it is to troubleshoot some video software that was lagging.

I know how to change them. But you did answer 1 question.

The 2nd question though was if I set it will Windows remember the settings upon reboot?

Ah. Right. I'm pretty sure it will remember upon reboot.

Actually, I think affinity is one of the process settings that does not get remembered on reboot.

Well dang. I guess that goes to show that it's not a very useful tweak.

Affinity may not be remembered but Infinity is (just not quite yet)
