Re: Python / Django slow ? Deciding my next technological stack

if you have so many uploads that all of yours workers are busy, so maybe you need more workers...

The rest of the uWSGI / gunicorn / whatever workers are available to handle the other requests.

If there are so many uploads that all of the workers are busy then there are ways to upload files directly to Amazon S3 (for example) from the browser without going through your server.

Just a little questions guys: when a user upload a file to server, and that file is a litte big and takes 3 seconds to be uploaded... what's the proper way, if possible, not to block the entire system for these 3 seconds so the server can serve other users while the upload is taking place. Should this be done in code with things like asyncio, or server with uwsgi workers ?

Unless you are producing web-scale sites (gmail, ebay, instagram), the
speed of your website will depend more upon what you do with a
framework than the framework you choose.

If you are producing web-scale sites, then whatever framework you
choose you will need to make the right design decisions and/or
compromises.

Even with the best framework in the world, if you design the
architecture of a website poorly, the website will be slow.

Even less important than the choice of framework is the choice of
hosting container for your framework. If you ever get to the point
where the speed of your wsgi container is the thing that is holding
you back, well done, now you should spend some time looking at it.
Until then, use the way that is easiest for you.

Cheers

Tom
