pl_subcalls.d - measure Perl subroutine calls using DTrace. pl_subcalls.d This traces Perl activity from all running programs on the system which support the Perl DTrace provider. Filename and subroutine names are printed if available. Any Evolving - uses the DTrace Perl provider, which may change as additional features are introduced. Check Perl/Readme to see what version these scripts are based on.
