For profiling your code there's perl's very own profiling tool `Devel::DProf` (and `Devel::SmallProf`), and you can find an article on the matter at Ovid's Devel::Dprof is your friend. As for accurate measurements of memory usage there's Elian's marvellous `Devel::Size`, this has to be hooked in manually, but with the likes of the `Hook::` modules, this shouldn't be too tricky. There's also some nodes about in the monastery on profiling your perl code. HTH `_________ broquaint`	[reply]

Try a Super Search and CPAN search for "Profiler" and especially Devel::DProf.	[reply]

The Devel::DProf module can profile CPU usage. I'm not sure what you could use to track memory usage (other than say 'top').	[reply]

Another option is Devel::Profiler, which is compatible with Devel::DProf, but will work in a CGI/mod_perl environment.	[reply]

On the memory checking front GTop can be useful. You might also find the performance tuning section of the mod_perl guide useful reading. It's not all mod_perl specific.	[reply]
