I was wondering just now, how well perl code can cope when its under constant use. Im refering to its ability to process a lot of information and cope better than some other languages like Java or C++.

You've lost me. It sounds like you're talking about Perl like it's an internal combustion engine or something similar. Certainly, engines wear out and eventually die. A piece of software isn't like that. If you're testing to see if the value of $foo falls inside a particular range, that's going to work whether you do it once or a million times a day, for as long as the platform has power.

Do you have an example where a particular language starts to wear out under heavy load? I'm just treally not following the train of thought that lead to this question.
