perl-Devel-NYTProf

Devel::NYTProf is a powerful, fast, 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 supported systems

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

Captures source code, including string evals, for stable results

Trivial to use with mod_perl - add one line to httpd.conf

Includes an extensive test suite

Tested on very large codebases


NYTProf is effectively two profilers in one: a statement profiler, and a
subroutine profiler.
