Also, Rails scales perfectly fine as a stateless web front end. If you have those scaling challenges you need an underlying architecture to handle it, not a silver bullet language.

If you need raw single process performance especially with parallelism then you probably should look beyond ruby. But the whole Rails doesn’t scale because Twitter meme is asinine.

Yeah. Not to mention that it is trivially easy to scale web apps horizontally. So the real bottleneck is the data store, not the programming language you used for your app.
