Scumbria,

Running two threads on two processors at half speed can be faster than running two threads on one processor at full speed.

The reason is that you have twice as much cache, and fewer context switches. All versions of Windows going out into the future support multithreading.

I think this scenario rare. You must have a fully utilized system with threads being independent. Under normal circumstances, CPUs are lightly loaded, and what you care about is that in the short periods, when the CPUs are not idle and are actually doing something, you want to get the result ASAP.

One 2 GHz system will exhibit much lower latency than a system with two 1 GHz CPUs.
