We will focus on muti-threading in a later chapter; however, now is a good time to mention that memory problems will reduce the performance you expect to gain from multi-threading. If it is true that we have reached the end of Moore’s law, then the only way for us to continue gaining performance in applications is to split work between processors. Multi-threading does not solve memory issues, in fact, multi-threading usually complicates memory and causes more problems. For more information, read the following chapter on multi-threading.
