If you decide to go this route, you might like to apply
http://www.freebsd.org/cgi/query-pr.cgi?pr=99800

By default gmon.out is overwritten by each process so you will only
get the output from the last process of a given name. My patch
optionally saves the profiling output each process in a separate file.
gprof(1) can already accumulate the output from multiple files so this
patch gives you the ability to profile multiple executions of a single
executable. You will still need to glue together the profiling
results from each executable.
