I think it is too low-level tool to use for performance monitoring. It
might be good for some detailed introspection or troubleshooting. I
think the python profiler gives quite good information about where the
time is spent.
I use a special query parameter to dump the profiling information of
handling a single request using hotshot profiler.
(scroll to the bottom to see the output of the profiler).
