When you profile you find out where the important things to tune are - the really slow things that actually matter.
But what if you've already tuned the important things? We're talking about a script that probably won't exceed 30 lines so it's not exactly difficult to maintain.
Benchmarking is a useful tool but it's nearly useless as a way to figure out what's worth spending time optimizing.
Yes, but it is useful in that it tells you how to optimize what you've already decided to optimize. I'd love to write it in C, but 1) I don't know C. and 2) I don't know of any webhost that allows compiled programs without a dedicated server.
