* 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 WWW: http://search.cpan.org/dist/Devel-NYTProf/ PR: 128255 Submitted by: Vladimir Timofeev <vovkasm at gmail dot com>

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
