Last time i've used it it was working but I dont think it is really useful now
(from my POV) because
you cant have a global view of the system with it and all other reports overlap.
With the current state you have:
- top mode for fast lookup
- text output (replace gprof for me)
- kcachegrind

How does one profile one's code on freebsd-amd64?
It seems that gprof is broken.

I would suggest using hwpmc for profiling:

# pmcstat -R /tmp/samples.out -G /tmp/penetration.txt
You can also get pmcstat to generate gprof-compatible output with -g,
but I never use the mode so I'm really not sure
