Just noticed that on my (low-end) laptop I get fairly high CPU usage from the browser tab for https://programming.dev
So thought I look what it’s doing via Chromium’s DevTools and there is a constant stream of activity. Looking at the websocket messages, it looks like it’s syncing all messages from the server (even for communities I am not subscribed to) to my browser tab (probably every time I reload the page?)
Seriously, that can’t be how it’s supposed to work - and certainly won’t scale? What is going on? Any ideas?
Just one random message from the Websocket (and I am certainly not subscribed to “animals”):

I agree that I suspect is websockets. From the source
