[noob question] Besides a GPU rig I also run a miner on my core2duo laptop sometimes just for fun (cpu only). I've noticed that ufasoft does around 3x - 4x the Mhash that CGMiner does. Any idea why or how I can get CGMiner to match the performance?

Install a 64-bit linux distro instead of running Windows? (This is just a guess, the latest cgminer seems to come close to ufasoft on core 2 and older Intel processors in 64-bit Linux, but apparently [based on an earlier post in this thread] cgminer uses 64-bit optimizations to achieve that and doesn't have similar 32-bit optimizations coded). The Windows binary is only written for 32-bit, so if I am correct in my assumption that your are running Windows, that would be the easiest solution. The much more complex ones would be to either a) compile a 64-bit Windows version if you are running a 64-bit Windows OS or b) optimize the 32-bit code and compile a new 32-bit version.

Oh, and in either Windows compilation case, you'd also have to modify other code to get cgminer not to waste more than one core's worth of cpu on whatever it does in Windows that it doesn't do in Linux (even when only GPU mining in each).
