We can run full fledged games at 240 FPS and yet,
websites and apps lag
This problem is real, but addressing it in the context of Ruby is misguided.
Slow websites?
It's the overall system design of the web. Running a bunch of untrusted sandboxed code, retrieved asynchronously from potentially dozens of sources?
Yeah, that's gonna be slow.
Replace all the Rails sites with assembly code running on bare metal if you like, it's not going to change anything.
Ruby on Rails is plenty fast. You can serve up static pages in a few milliseconds. If they take longer than that, it's because you're doing a bunch of work at the database layer or some other work outside of Ruby.
