I'm assuming this is platform specific. It's totally smooth for me on a M1 MacBook Pro. Thats with a bunch of tabs open while on a zoom call (gotta do something to pass the time during standup). I find it annoying for other reasons, but I'm not seeing any perf issues on the page.

edit... reading through the other comments I see LOTS of people are having this issue. Not sure why I'm the lucky one, but I went back and clicked through all the pages, still no perceivable lag at all.
