Ruby performance limitations compared to alternatives
8/10 HighRuby's runtime performance significantly lags behind Go, Rust, Node.js, and Swift, making it unsuitable for production systems where performance is critical. Despite language improvements via YJIT and MJIT, raw speed remains a critical limitation at scale.

Collection History
Ruby is not a compiled language, so it doesn't have the raw execution speed of something like Rust or Elixir. You can scale Rails, but it usually involves throwing more servers at the problem, not squeezing every ounce of performance out of the box.
It's just so slow compared to other language. It's something that's a little disconcerting that in all these years the core ruby team hasn't seemed to fix the performance issues in the language. The one language/framework that's truly super fast and easy to get something built, just happens to be one of the worst at scale.
