“You can increase the performance of a Linux system in various
ways, and one of the most popular methods is increasing the
performance of the processor. An obvious solution is to use a
processor with a faster clock rate, but for any given technology
there exists a physical limit where the clock simply can’t go any
faster. When you reach that limit, you can use the more-is-better
approach and apply multiple processors.”
