I guess I'm being selfish as a developer and thinking about my own ergonomics and dev experience. Is Rails as fast as .NET? Probably not, but if it can serve web pages in under 200ms, it's fast enough.
Agree, and I wouldn’t trade rails for a perf boost if I had to go to a horrible Java web stack (or a horrible C# web stack prior to .NET core)
Right now though, the dev ergonomics and productivity of .NET core are not actually very far behind rails at all, so you can serve your pages in 2ms instead of 200ms without suffering for it.
In some regards actually, perf helps a lot. Running a large bank of tests for example - those are going to complete a LOT more quickly in .NET which means you can iterate faster and have a better dev experience
