I am having a lot of issues with Facebook load times and scrolling. I finally disabled Adguard for Facebook and it's a very big improvement in speed. I use Chrome 96.0.4664.110 with Windows 10. I have a Core i7, 16gb of ram. Some sites can take up to 8-10 seconds to load, disable Adguard and they load instantly. My internet is 1000 meg with AT&T uVerse wired connection to the desktop.
