Did you look at the actual script?

He is using a grand total of 2 wget processes. Hardly a reason to switch to LWP.

I stronly doubt that using Archive::Rar which has to mediate between C and Perl data structures is going to be a win over using an external binary for a simple uncompression.

He can save mv processes by using xargs.

Most of his sed filters can be condensed.

Granted, a mediocrely written shell script is going to be much slower than a mediocrely written Perl script, but for the tasks it's doing, shell seems like a more than decent tool.

Makeshifts last the longest.
