There are many things that can be done to improve the performance of code, but the only guidance we can give you without seeing the code in question is: * read [perldoc perlperf][1] * profile your code: [Devel::NYTProf.pm][2] * benchmark different algorithms: [Benchmark][3] * rewrite critical sections in XS or use XS based modules ([perldoc perlxstut][4], [perldoc perlxs][5], [perldoc perlguts][6]) [1] : http://perldoc.perl.org/perlperf.html [2] : http://search.cpan.org/dist/Devel-NYTProf/lib/Devel/NYTProf.pm [3] : http://perldoc.perl.org/Benchmark.html [4] : http://perldoc.perl.org/perlxstut.html [5] : http://perldoc.perl.org/perlxs.html [6] : http://perldoc.perl.org/perlguts.html -- Chas.
