Optimizing Perl

An anonymous reader writes "Perl is an incredibly flexible language, but its ease of use can lead to some sloppy and lazy programming habits. We're all guilty of them, but there are some quick steps you can take to improve the performance of your Perl applications. This article looks at the key areas of optimization, which solutions work and which don't, and how to continue to build and extend your applications with optimization and speed in mind."

And then stress-test with Slashdot ...

[xmas2003]

I use Perl for my halloween webcam - same code is used in the christmas webcam ... and thought I had it in pretty decent shape ... until the Slashdot thundering herd descended on it and gave it one heck of a stress test.

For instance, flock is your friend ... and as I outline in my slashdot effect analysis you had better be prepared to handle race conditions. Ignoring the web server overload (mod_perl would have helped here), the code actually hung in there fairly well as I've learned from past "mistakes" when I've seen some pretty funky error messages crop up ... but even this time around, there was two minor corner cases I failed to account for (had never been "tickled" before) ... but those are fixed now so I'll be "more" ready if my christmas lights show up on Slashdot again ... but then again, you are never really "ready" for Slashdot! ;-)
