Okay, I admit I'm making a comment almost solely to have
Andrea, Andreas and Andrew in the same thread.

I've seen superlinear and sublinear performance for this.
Superlinear when the problem fits into 2x cache size but not
1x cache size and is nicely decomposable, and sublinear when
the data doesn't have good processor affinity.

Do I get an A for Andre.*?  :)
