Ruby may be slower than other languages, but generally speaking your scalability issues will never be solved by rewriting in another language. A rewrite may give you a temporary relief if the runtime of your new language is say 10% faster than your current one. This is not a long term solution though, and for many startups in hyper growth state, this will just give you a few more weeks of runway until you run into the next roadblock. Your solution to scalability issues should almost always be system redesign, not component rewrite.
