Artickle: speed up lead to avoiding cache misses which lead to further speed up which lead to further less cache misses This kind of interaction is important to keep in mind. It applies to all kinds of caches in all kinds of situations. To some degree even the instruction and data caches of modern cpus. But most interesting is that in complex systems in (very very) rare cases the "whole system effect" can go the other way around too (due to a now faster components trashing the cache for other components in a way which makes the system as a whole slower).
