I see that the more stressful days approach. I'll stick with single processor and count on my buddies at intel to raise the bar by 75% every year without having to introduce the instability that SMPng will undoubted suffer with for long periods. A 1.5Ghz processor can outperform 2 fully saturated PCI buses, so its not going to help much in the networking world, which is where I live. Processing power is already exceeding the busses capabilities. Its nice to have a processor for user space and one for kernel/interrupt space, but going beyond that to seriously adulterate the OS to squeeze a few extra cycles in a world where processors are jumping 20% in speed every few months seems counterproductive. You dont put 2 engines in a car to make it faster, you get a faster engine. It seems that there is a lack of foresight here...you're losing a year or more of engineering time and before SMPng is stablilized the IA-64 will be out and most multiprocessor applications will be rushing to move over to that.
