How many cores does your machine have, 10, 18? Your async Python code uses just one of them. That isn't a bug in asyncio. That's the design, and optimizing event loops to be faster by 20% doesn't…
Giovanni BarillariGuestMichael KennedyHostI recently did a post over on my blog, personal blog, calling cutting Python web app memory by 31%.
And I did a ton of analysis and stuff on how I was running Grandion and different things, just how I was running Python.
And I think this is going to be a good lead-in to where we're going as well.
I got it to where I was using 120, 1.3 gigs, let's say, for TalkPython, training the courses specifically, which is, and people are like, oh, it's just a little courses thing.
totally small project.
But down
One of the
main reasons I did that as a way I want to kind of want to lead into like this where we're going is I said, well, the way gradient works is for each.
Either you can make multiprocesses that are single threaded or could do multiple threads and then it'll create a separate interpreter for each one.
