Firefox added Python support in the past and there was no uptake. Brendan Eich has a hnews comment on it.

I think 2x-3x perf improvement /is/ possible. I mean we have the example of javascript that went from terrible perf to almost native parity. Of course Mozilla & Google each dedicated an entire team to get there.

We already have the example of PyPy too which /today/ averages a >5x (http://speed.pypy.org/) speed up with CPython!

It didn't have the ecosystem of C extensibility and mature extensions Python has, which drive much of its adoption in e.g. scientific computing (a big factor for Pypy having trouble making inroads).
