Was running a rails monolith with up to 300 concurrent users and a huge growing database on a $20 VPS and free cloudflare. Sure it only had highly optimized queries (something rails makes kinda easy too), but that's what you are supposed to do anyway. There wasn't ever a need to recode to run it on a $10 instance. Nether do I think 99% of all database driven projects, including mine, are ever going to reach as many concurrent users. IMO: talking about performance for ANY major coding stack is just premature optimization
