Maybe my log on times are different than others, and I’m just about computer illiterate. But fwiw, I’m using Firefox as my browser with it’s pop up blocker activated, and I’ve seen no slowing on this website at all.
Not of course related to website speed. But there is an issue with the upper left hand back button on only this website though. Sometimes it takes 3-4 tries before it will work. And that’s been going on for at least a few months.
