We are not using PyPy in the company I work (https://www.demonware.net) at the moment and we are handling way more requests per second, with also very small response times (less than 10ms in most cases, but it depends).
The bottleneck is usually DB work, so PyPy is not a great help there.
Bottomline: Number of requests (scalability) and response times (performance) are more a work of architecture than using a particular language. And Python can be actually quite fast (fast enough)
