Shopify is built using Ruby on Rails, they successfully handle enormous traffic spikes during Black Friday sales without issues.
So I think we're good with performance.

Also remember that Shopify didn't start out making billions. They started as a small side project on a far, far slower version of Ruby and Rails.
Same with GitHub, same with many others that are either still on Rails or started there.
You can optimise things later once you actually have customers, know the shape of your problem and where the actual pain points are/what needs to be scaled.
To me, I care a ton about performance (it's an area I work in), but there's not a lot of sense in sacrificing development agility for request speed on things that may not matter or be things people will pay for. Especially when you're small.
>On Rails, the most heavy page has a P95 duration of 338 ms. There is of course room for improvement but it's plenty snappy.
I guess everyone will have different opinion on P95 at 338ms. The great thing is that we are getting cheaper CPU Core price and YJIT. As long as this trend continues, the definition of Fast Enough will cover more grounds for more people.
