I'm not at all familiar with McKinley, but would it be possible to run a version of Crafty compiled for 32-bits on a McKinley and compare that to a Crafty compiled for 64-bits on McKinley? Is this a dumb idea? If this isn't possible, then it's going to be difficult to tell where the performance gain is really coming from. -Keith
