in reply to Profiling/Benchmarking web applications

Use DBI::ProfileDumper::Apache .

Quoting from the docs:

DBI::ProfileDumper::Apache - capture DBI profiling data from Apache/mod_perl


Add this line to your httpd.conf:

PerlSetEnv DBI_PROFILE DBI::ProfileDumper::Apache

Then restart your server. Access the code you wish to test using a web browser, then shutdown your server. This will create a set of* files in your Apache log directory. Get a profiling report with dbiprof:

dbiprof /usr/local/apache/logs/*

When you're ready to perform another profiling run, delete the old files

rm /usr/local/apache/logs/*

and start again.

Additionally, if you wish to fine tune your profiling needs, see Speeding up the DBI for some examples on how to include profiling code (using DBI::Profile) in your application.
