Hardware Performance Monitoring Counters, George Neville-Neil
[nycbug-2008-11-05.mp3]
(Audio generously recorded and processed by Nikolai Fetissov)

Many modern CPUs provide on chip counters for performance events such as retiring instructions and cache misses. The hwpmc driver and libraries in FreeBSD give systems administrators and programmers access to APIs which make it possible to measure performance without modifying source code and with minimal intrusion into application execution. This talk will be a brief introduction to HWPMC, and how to use it.

About the speaker:
George Neville-Neil is the co-author with Kirk McKusick of The Design and Implementation of the FreeBSD Operating System. He works on networking an operating systems for fun and profit.
