It can do a lot more and I didn't say it was impressive. What I am saying is that Python won't be the bottleneck for the vast majority of websites and that it will scale. And the raw performance of the underlying language is rarely the thing you need to worry about when writing a website. If you like Python then there are a lot of robust options available to create a product that scales.
A billion requests per month is 400 requests per second. My toaster can do better than that :)
Not to say that your product isn’t capable for many use cases, but the fact that the 1krps range is something impressive in Python world is indicative of the issue: Python is not built for speed, it’s built for convenience, and increasingly it’s competing against more modern languages that offer both.
