For my dinky dual core laptop, I suspect you're right, but for a more powerful laptop, I'd expect spread/don't to be noticeable.

If I had a powerful laptop, I'd kill irq balancing, and all but periodic load balancing, and expect to see a positive result. Dunno what fickle electron gods would _really_ do with those prayers though.
