Here\'s the deal.

I have a OS X iMac running a T7600 Merom Core 2 Duo at 2.33GHz, FSB 667MHz, cache 4MB, RAM 3GB. Average work unit speed for 160 year model is 1.27 secs / TS.

Also I have a Win XP Pro SP2 machine, E6750 Conroe at 2.66GHz, FSB 1.33GHz, cache 4MB, RAM 2GB. Average speed 1.82 secs / TS.

What gives? I\'m getting nearly 50% more speed from the notebook chipset than the desktop one? Neither machine is stressed with respect to RAM usage. Strange.

This was noted during testing of the Mac models. (On the beta test site.)

The new Intel Macs run the models a lot faster than Windows / Linux machines.
Something to do with the design of the Mac. But the Macs have a very limited stack space, which can cause crashes.
