To a degree, but unless you need to serve a literal thousand-plus humans per second (AI bots don't count, modern problems require modern solutions and "your own" is not a solution, use an AI maze SaaS), it's still irrelevant: every modern CPU and even inefficient scripting language can serve hundreds of concurrent connections as long as the content itself is proper content instead of "modern" nonsense bundles. Sending pre-compressed html and css (with a sprinkling of JS at best to enhance the experience after it's already in the browser) is kilobytes of work at most (irrespective of how much it unpacks to on the client). The biggest lie the modern web sold us is that information needs to be packed up in complex datatypes and be interpreted on the client before it's information again.
