Hardware Performance Monitoring Counters

6:30pm, Suspenders Restaurant

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.

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.
