What is a NUMA machine. How does being NUMA affect performance or MIPS values. 2. I still think that MIPS is a good measure of performance, if used within the same line of computers. If you compare the z/890, or z/990 models, MIPS gives a good relative value of what to expect. If you compare them to a 9672, it probably isn't as relevant. The fact the IBM, when announcing new hardware, usually prints MIPS in their charts says that it is still a valid number. I'm not saying it is best, or that there isn't problems with MIPS, but the MIPS numbers still make more sense to me than any other indicators.
