well, i think this thread has drifted away from its original question, which was asked toward ms os's efficiency and not their stability. when it comes to processors and smp, a dual-processor machine will most likely be less efficient than a single processor machine, though it will perform tasks more quickly. a windows nt machine running two processors will only use approximately 80% of the second processor, because the operating system is inefficient in that it requires 20% of the second processor just to manage that second processor. on the other hand an operating system like, say, Be, only wastes about 2% of the second processor because it was designed from sqaure one to support multiple processors, and supports n processors with equal efficiency.
