hazel hogs cpu

When Hazel starts sweeping, it hogs BOTH processors in my G4 Dual. It shouldn't oughta take up so much cpu--slows everything else down. Is there a way to change this so it behaves a little better? Thanks.

I really can't provide support for a version that old at this point. App Sweep can be resource intensive as it's searching a lot of files and not much can be done about that, especially with an old version on old hardware.
