I have a low cost VPS (actually two in two different pre-AI datacenters) and it runs fine. I use nginx to serve the web pages, and the content is about 99% static content.

The vBulletin and PHPbb style forums have issues with slowdown (I haven’t had a forum since 2015; even back then those forums were overrun with spambots), but static content on a nginx site can be served lightning fast.
