Thanks for the link.
It's not exactly infinite scrolling or anything like that, it's an app (kind of, browser extension), RSS reader to be precise, and just by importing my sources list and downloading currently available articles ir goes to over 3000 articles. Selecting "all feeds" surely renders quite a big list.
It's a legacy project I picked up since it was abandoned and cleaned up a bit, there was even an attempt at handling long lists better but it was actually working slower than naive list everything, approach and was glitching quite often. Currently performance isn't terrible but if there was some easy way to improve it I'd gladly use it, I'll do some more research in this matter to see what can be done.
