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
