Until the day 100% of browsers support 100% of features with 100% correct implementations, or we have only one browser, it will keep working like this.
It should not be a FIFO. They probably want diversity of countries, ISPs, devices, etc. According to your profile you're located in China so they're surely not short of Chinese test subjects for a VPN ;)
When you write Python you already know you're throwing the performance out of the window. In fact based on my experience those numbers are pretty good.
It's trivial to get 1kr/s with the simplest of wsgi flask behind nginx without touching anything. But these "comparisons" are meaningless without asking what "serving the request" is about.
as much as i love the python ecosystem and django in particular, the parent is definitely correct.
Don't ever choose python for performance. Its definitely fast enough for most things, but its just not the tool to leverage if you actually need performance.
Its wonderful if you just want to get shit done though, there are just so many good libraries around that you can use to get your project finished without committing several times the effort it takes in other languages
You can get excellent performance in Python, but at the cost of dev effort – a very deep understanding of the interpreter (and replacing some loops with Cython) would do wonders.
