devel/p5-Devel-NYTProf 6.14nb5 NetBSD

The Perl 5 module Devel::NYTProf 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-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 codebases NyTProf is effectively two profilers in one: a statement profiler, and a subroutine profiler.
