====== 2009.10.03 - CPU caches know-how ======

today i've wrote short article summarizing and showing code examples of how do modern CPUs' caches affect overall performance and how to use it effectively -- [[:docs:cache_usage_effects_on_modern_cpus:cache usage effects on modern CPUs]]. it is based on very interesting article by [[http://people.redhat.com/drepper|Ulrich Drepper]], {{http://people.redhat.com/drepper/cpumemory.pdf|What Every Programmer Should Know About Memory}}. you can be surprised how much CPU cache and its proper (though mostly implicit) usage affects speed of modern CPUs... :)
