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.
