[cgiapp] profiling

[William Bulley]

In year's gone by, one could profile the execution performance of
a C program by instrumenting it at compile time for the purposes of
using prof(1) or gprof(1) subsequently to get run time statistics.

I have found DProf.pm and DProfPP.pm on CPAN (thanks Ron!) which it
seems is a comparable solution for Perl scripts at the command line.

What I am wondering about is this: is there a way to profile a CGI
Application script given that doing same from the command line is
problematical, if not impossible?

I recall the way that prof or gprof worked was by sticking a statement
or an instruction before or after each procedure so that a bucket for
that procedure was timestamped and the count increased for that bucket
(for that procedure) - all this based on the program runtime stack.

Later you would run prof or gprof and you would get simple statistics
such as which procedures took the most time, etc.
