Of the 3 main languages for web dev these days - Python, PHP and Javascript - I like Python the most. But it is scary how slow the default runtime, CPython, is. Compared to PHP and Javascript, it crawls like a snake.
Pypy could be a solution as it seems to be about 6x faster on average.
Is anybody here using Pypy for Django?
Did Clubhouse document somewhere if they are using CPython or Pypy?
When using something like Golang, I have apps doing normal CRUD-ish queries at 10k QPS, on 32c/64g machines. For most web apps, 10k QPS is much more than they will ever see, and the fact that it is all done in a single process means you could do really cool things with in-memory datastructures.
Instead, every single web app is written as a distributed system, when almost none of them need to be, if they were written on a platform that didn't eat all of their resources.
I've been told off in code review for using Python's concurrent.futures.ThreadPoolExecutor to run some http requests (making the code finish N times faster, in a context where latency mattered) "because it's hard to reason about".
People don't use python because they want performance. People use python because of productivity, frameworks, libraries, documentation, resources and ecosystems. Most projects don't even need 10k qps, but instead most projects do need an ORM, a migrations system, authentication, sessions, etc. Python has bottle tested tools and frameworks for this.

You can compile it to JS or to Webassembly. But you can do that with every language.
Way to miss the point.
It isn't any macros. Not sure what you're talking about.

Yeah that does suck but fortunately ESLint and Typescript have options to prevent most of them. If you use Deno they're enabled by default.

Also true, but we're comparing it to PHP and Python.
