Agree.

I don't think folks think clearly about how their setup scales computationally when they are choosing their stack. I've been writing a lot of software designed for drop-dead simple self-hosting lately (can run CGI-bin or as a standalone server, based on the env it's invoked in), and I put my own instances behind CGI, keenly aware of the risk on the open internet. But I design .htaccess so that the main server is hitting caches for anything anonymous. This works Just Fine for hitting the HN front page in my experience on a 1GB VPS, since the request never even makes it to my Python code.

I think folks just don't prioritize these sorts of optimizations.
