Too much that's the problem. A comparison won't address the issue a change in settings will if we have a form of control on the feed because each request from a relay is a constant pull the feed from that & this relay. There needs to be an option to change it from constant to a customizable number if the user wants it to.
I would keep mine off & only do manual pulls like how Instagram use to have. It would just be a swipe down from the top then the feed refreshes.
