Devel::NYTProf Description

Powerful feature-rich Perl source code profiler The Devel::NYTProf module is a powerful feature-rich Perl source code profiler. * Performs per-line statement profiling for fine detail * Performs per-subroutine statement profiling for overview * Performs per-opcode profiling for slow perl builtins * Performs per-block statement profiling (the first profiler to do so) * Accounts correctly for time spent after calls return * Performs inclusive and exclusive timing of subroutines * Subroutine times are per calling location (a powerful feature) * Can profile compile-time activity, just run-time, or just END time * Uses novel techniques for efficient profiling * Sub-microsecond (100ns) resolution on systems with clock_gettime() * Very fast - the fastest statement and subroutine profilers for perl * Handles applications that fork, with no performance cost * Immune from noise caused by profiling overheads and I/O * Program being profiled can stop/start the profiler * Generates richly annotated and cross-linked html reports * Trivial to use with mod_perl - add one line to httpd.conf * Includes an extensive test suite * Tested on very large codebasesNYTProf is effectively two profilers in one: a statement profiler, and a subroutine profiler.SYNOPSIS # profile code and write database to ./nytprof.out perl -d:NYTProf some_perl.pl # convert database into a set of html files, e.g., ./nytprof/index.html nytprofhtml # or into comma separated files, e.g., ./nytprof/*.csv nytprofcsv Requirements: · Perl
