12M is certainly respectable. It will go up in a 64 bit mode machine. I get about 5M on my core2 duo 2.0ghz laptop (one processor two cores).

Nolan, is this version of crafty compiled using GCC (or something else)? Is it running linux?

Sorry I missed your other post. I see that your crafty version is Windows based and compiled with Visual C++
