perfmon is intended up be used for performance tuning in production
multiprogrammed environments, although it also has system-wide and
per-cpu counting modes. So you can have multiple people using the
counters inside their processes and threads and all the counts are
preserved as the state and the full 64 bit values are part of the
process context, for the per-thread monitoring modes.

How does perfmon differ from the perfctr project, which seems to be doing something very similar? See http://user.it.uu.se/~mikpe/linux/perfctr/



Anyways, glad to hear other folks are as interested in performance
analysis!


We most definitely are, in particular we are looking for good tools with which to analyse threaded applications running on multi-threading hardware. Does this version of perfmon support threaded code?
