Loading two DLLs which provide two different functions to two different threads will not run faster than one DLL with both functions in it. The point you are thinking about is: How is the CPU-time shared between these both treads. Well, that is something you may influence. the Sleep function at least gives the remainder of the current time-slice to other threads waiting for execution and last, but not least there is something named a process-priority which can be lowered easily. putting sleep(0) calls into the right places of the long enduring function may to the task already. Tampering with the priority can affect overall system performance, so be careful! have fun Bob
