My group has been wanting to do execution profiling of some I/O 
intensive applications on our SPARC stations, and the numbers that
would really be of interest are the real-time seconds spent in each routine
and its children, including time spent blocking for I/O to finish.  The
utilities "prof" and "gprof" generate the format of reports we would like,
but they always base their numbers on virtual CPU time spent in each
routine.

Question: is there a way to get "gprof" to use real-time instead of 
virtual-time for its sampling, or is there another profiler available
(at moderate cost) which would measure want we want?

Thanks,
