Apache::DProf problems
I've installed Apache::DProf, but it seems hardly any of the calls are
profiled. dprofpp shouws MOF::Dispatcher::handler as taking up 100%
of the time, but there is no information recorded in for calls within
that function. MOF::Dispatcher::handler is calling thousands of other
functions and there is absolutely no record of any of those calls in
tmon.out.
Any ideas an what's going on? I'm running mp1.27 and compiled it with
EVERYTHING=1
[root@loopy modperl]# dprofpp logs/dprof/2734/tmon.out

You probably compiled that code before you initialized the debugger.
Add a call to Apache::DB->init before you load your modules, as
described in the Apache::DB docs.

If you post your conf, we could probably help you more.

Doesn't matter. You just have to initialize the debugger. I do this by
calling Apache::DB->init because I don't want to actually profile
anything during startup but I do need the debugger turned on when I
compile code at startup for DProf to work.

i'll double check, but i'm fairly certain it's loaded first.
what if a module is loaded after the fact, but like this: eval { use
$module };
some modules are dynamically loaded at run time depending on certain
situations.

Remember that any PerlHandler that was pulled in before Apache::DProf in the
httpd.conf or startup.pl file will not have code-debugging information
inserted. Make sure that you load before any code that you plan to profile.
