Devel::NYTProf is a powerful feature-rich perl source code profiler.
o Performs per-line statement profiling for fine detail
o Performs per-subroutine statement profiling for overview
o Performs per-block statement profiling (the first profiler to do so)
o Accounts correctly for time spent after calls return
o Performs inclusive and exclusive timing of subroutines
o Subroutine times are per calling location (a powerful feature)
o Can profile compile-time activity, just run-time, or just END time
o Uses novel techniques for efficient profiling
o Sub-microsecond (100ns) resolution on systems with clock_gettime()
o Very fast - the fastest statement and subroutine profilers for perl
o Handles applications that fork, with no performance cost
o Immune from noise caused by profiling overheads and I/O
o Program being profiled can stop/start the profiler
o Generates richly annotated and cross-linked html reports
o Trivial to use with mod_perl - add one line to httpd.conf
o Includes an extensive test suite
o Tested on very large codebases
NYTProf is effectively two profilers in one: a statement profiler, and a subroutine profiler.
