Job Performance

I have an interactive process (a group of programs, bound and otherwise)
that is not performing as well as I would like.  I would like to know when
certain key events are occurring, such as the points in time that various
programs are called, when files get opened, etc.  If I can establish such
timings, it will allow me to identify the long-running processes, and I
will know where to focus my performance-enhancement efforts.

I know I could insert a process to log timestamps to a file at various
points in the programs, but I'm hoping for something a little less
invasive.  TRCJOB to an outfile probably has the information I'm looking
for, but it has so much more that I can't make sense of it with the naked
eye.  Any suggestions?
