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 faste…

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.
