<br><br>I usually use the Carp module classes to give stack traces (confess, croak):<br><br><a href="http://perldoc.perl.org/Carp.html">http://perldoc.perl.org/Carp.html</a><br><br>I believe that Carp is now internal to Perl, and it is mature, but, as with many object oriented modules, there is some overhead involved when using them.
<br><br>There is also Dave Rolsky's Devel::Stacktrace:<br><br><a href="http://search.cpan.org/~drolsky/Devel-StackTrace-1.15/lib/Devel/StackTrace.pm">http://search.cpan.org/~drolsky/Devel-StackTrace-1.15/lib/Devel/StackTrace.pm
</a><br><br>Usually, when I want a stack trace, I am debugging, but I see your question is concerned w/performance, so I am assuming that you want a dump to a log someplace while the script is executing, and so the traditional perl functions die and warn, probably aren't much use.
<br><br>A perl profiler can help w/monitoring performance with scripts.<br><br><a href="http://search.cpan.org/~ilyaz/DProf-19990108/DProf.pm">http://search.cpan.org/~ilyaz/DProf-19990108/DProf.pm</a><br><br>hth, <br><br>
