1. No matter what programming language or technology you use, if your software fails to make effective use of the underlying CPU caches, your system's performance will suffer. A lot. This session provides a wide-ranging overview of CPU caches, how they operate, and how that affects high-level decisions on things like data structures and traversal strategies. Both single- and multi-threaded execution are considered. Specific topics include different cache types (data, instruction, TLB); private and shared caches; cache lines and speculative prefetching; false sharing; and cache-friendly program organization, data structures, and traversal strategies. If you care at all about performance, the information in this talk is essential.
