I ran the Perl program from the shell and took the same time of 40 seconds

Hello Oscar,

I don't have much idea why you are seeing such a big difference in response time.
But I do have some further questions that may be useful to you or to someone else on the mailing
list that may have a clue what is happening.

First of all, logic would seem to indicate that if we are seeing this big of change in the
result, then something must have changed in the scenario.
A suggested task would be to try to figure out what is different.
Could there be any new programs running on your system that might be causing contention of
some sort?

If you are using an intranet classified network, does this mean that you are using network
protocols other than TCP/IP?

Since you are using perl scripts, are you also using mod_perl?

We would like to discern which part of the request/response round trip is using up the extra
Is the time lost in the Apache httpd server, mod_perl, the perl script or in the access to
the database?
Would it be possible to run your perl scripts directly from a shell and compare the response
time to the overall response time through the httpd server?
