config -p[p]

I normally use this script:

---
#!/bin/sh
sync

# Change to -rb for lower overhead lower quality low resolution profiling:
kgmon -rB

# Change to operation to be profiled if not just general system activity
# for 10 seconds:
sleep 10

kgmon -hp
gprof4 -u `sysctl -n kern.bootfile` gmon.out >zp
