I am interested to know how your web application pushed the performance limits of Python. You should be able to get thousands of requests per second, even out of a laptop running a pure-Python server. (I'd defend Ruby the same way but I don't know its details - I doubt it is very different, though) The bottleneck in almost any real web app is going to be the database, not the programming language. If you can't scale horizontally then your language choice is not your problem. If you can then what performance metric is going to show the inadequacy of Ruby or Python running on a few servers? Add the caching that you should be doing anyway and even slower Ruby/PHP/Python frameworks can perform quite adequately. I don't dispute that Go is a cool language but this seems like FUD.
