One tip for profiling with mod_perl:
If you preload your modules in httpd.conf (or a startup.pl called from
it), make sure you initialize the debugger before you load them or else
they will not show up in DProf output.
For example, put this before any PerlModule or PerlRequire statements:
<Perl>
require Apache::DB;
Apache::DB->init;
</Perl>
