When I need performance and I need to code complicated things, Perl is always my choice. I like the syntax and miss so much map and grep when I’m programing on with other languages. I used perl for every background task like matching millions of records, downloading giga bytes of xml with fork processes, writing daemons, ….

• The syntaxe
• Hashs, grep perl
• There is a module for everything in CPAN
• The performance, can be quicker than C because of the compilator optimisation.

• Mod_perl in Apache is complicate to configure, performace used to be not as great as php
