So I tried my scheduling software on my mac today. It took about 18 seconds to calculate my schedule on my duo-core 2ghz MacBook Pro.

My home WinXP 2.1ghz DuoCore2 based machine takes 2 seconds. A 9x improvement.

But the shocker... my work WinXP laptop with a 1.7ghz Pentium M, a MUCH slower machine, takes about 4 seconds.

Why is the Mac so much slower on compute intensive actionscript?

I've heard of it being slower on graphical animation type things, but not something like this.
