NAME Devel::FileProfiler - quick & easy per-file statistical profiler SYNOPSIS use Devel::FileProfile; DESCRIPTION Devel::FileProfile is a very simple statistical profiler. Unlike Devel::Profile, it will not slow down the execution of your program and it will not take forever to generate the profile results. On the other hand, the profile results are not nearly as detailed. To use it, just "use Devel::FileProfile" in any file you want profiled. When your program is done executing, it will dump a partial code-listing to STDERR with the percentage of time spent on each line annotated. It does statistical sampling so most lines won't be listed. The output format is: %%% line# code For each line listed, several lines of the surrounding code are shown to provide context. There are many improvements that could be made to this module. Feel free to make them and send a patch to the author. The module meets the author's needs as is. The code is very very simple. BUGS Devel::FileProfile uses $SIG{ALRM}. It is not currently compatabile with any other uses of $SIG{ALRM}. It potentially could know about things like Event and use them but it does not currently do that.
