> I wonder if anyone has studied the impact of latency on user behavior while considering the impact of user expectations from their typical connection speed. Whenever I see an article about page speed optimization, the assumption is that a user will give up if a page takes too long to load, ans that everyone gives up after X seconds. Usually X is about 7s based on a Nielson article from years and years ago. N=1 but I think I am quicker to close a tab with a website that does lazy loading and/or hide stuff for a blink second or three just after showing me the thing I am here for than a tab with a slow loading.
