In the next release you’ll be able to use the “start=no” option to avoid the need for the initial DB::disable_profile() call.

DProf is a subroutine-level profiler. (I’ll talk more about subroutine-level profiling vs line-level profiling in an upcoming post about the soon-to-be-released NYTProf 2.0.) [...]

is there any way to tell NYTProf to just sample just specific functions? I have a Perl program with a 20-minute init time (loading >25 GB of dictionaries) and only then come the functions I want to profile. Of course profiling during the initialization takes longer and generates a huge profile file, which I want to skip.

thanks, Michael

It’s just a matter of someone doing it. I believe Steve Peters, one of the contributors, is already working on it. Perhaps you could help him.

That looks very interesting, in fact extremely interesting! Read through the code and stumpled upon the “Currently there’s no support for Windows.”

Being a Windows user, that’s a bit off-putting ;-) I could imagine that it could be a development decision to get the module done but I hope it is something that can be changed over time. Is the problem simply a different API or is it more fundamental?

Did mod_perl measurement code gel in this release?

thanks! -g

NYTProf is used during development/maintenance to profile all the source code without changing it.
DashProfiler is for use in production by modifying specific parts of the source code to take measurements.
