Something I just realized, which though it is a simple revelation, I was missing it for a while... for anyone who does 
for(reverse sort @foo)

[download]
it is much faster to instead use a sort subroutine set up to return a reversed sort, i.e. 
for(sort {$b <=> $a} @foo)

[download]
$b <=> $a instead of $a <=> $b returns reversed list...

and use cmp instead of <=>

My benchmars show a SIGNIFICANT difference between the two...

just something I thought I'd share... many people probably realized this already

Update HAHAHAH, I wrote this just before I left, went home and just read Nathan Torkington's article in TPJ #20 about arrays, which says the same thing I do here... That's funny in my book.
