HISTORY

A bit of history and a shameless plug...

NYTProf stands for 'New York Times Profiler'. Indeed, this module was developed by The New York Times Co. to help our developers quickly identify bottlenecks in large Perl applications. The Times loves Perl and we hope the community will benefit from our work as much as we have from theirs.

DESCRIPTION

nytprofhtml is a script that utilizes Devel::NYTProf::Reader to create colorful HTMl formatted reports from Devel::NYTProf output.

The reports include dynamic runtime analysis wherein each line and each file is analyzed based on the preformance of the other lines and files. As a result, you can quickly find the slowest module and the slowest line in a module. Slowness is measured in three ways: total calls, total time and average time per call. Analysis is based on absolute deviations from the median.

That might sound complicated, but in reality you can just run the command and enjoy your report!

Note: You'll need to run your app through Devel::NYTProf debugger first
