something is wrong. no differences with MP2

Hey gang,
   We are finally ready to move to our mod_perl2 handler. I just 
finished running some tests against our old CGI (no PerlRun, no 
Registry, just plain jane CGI).

   The results were basically the same. I did 500 requests, 2 
concurents, and both scripts took about the same time.

   How can I find out what has happened? I just restarted apache too, to 
give the mod_perl version a clean recompile.

  Previous tests always showed at least a 50% speed increase over CGI.

Is there some tool I can use to find out what has been added that is 
slowing down our mod_perl? Or any ideas what to look for first?

Thanks,
Matthew

Both are reporting:

<!-- mod_perl/2.0.2 -->

Will look into Apache::DProf

The most likely answer is that something is wrong with your
configuration and both are running through the same CGI.  You should try
printing the value of $ENV{MOD_PERL} for both.

  Has anything changed in your setup since running the test the last
  time you saw a plausibly good result?
