>Other than some quite significant performance gains

I am aware that other languages perform better in benchmarks than, say, Python does. But in my experience, I've not ever found the speed of the language to be a bottleneck when I'm benchmarking and optimizing for scalability in a web app.

It's always something else. The database interface, the network, a crappy web framework, whatever. It always seems to be something other than the fundamental language that bogs things down.

I'll openly admit I might be missing something or that perhaps I haven't tried to scale high enough. I just don't get how it's relevant that x language is y times faster than Python when Python hasn't ever been the problem. There's always just so much more low-hanging fruit than the language.
