I'd like to write a Meditation on Perl optimization and profiling. I don't see too much discussion here about it, and I feel it's something that might be of interest.

Given that I can edit this node later, I figure I'll first ask for some sample code to use as an example. I'd like someone to point me to or send me a Perl application that:

• is something they wrote
• is not a CGI or database app
• has a moderate number of subroutines, rather than one big blob of code in main
• has not yet been optimized
• runs slowly enough to actually time
• is not destructive to data
• does not require more than 1Mb of disk space to run

My strategy will be to optimize the code step by step, detailing the process and code changes, and showing the resultant speed increase (or memory reduction)

Thanks!
