I experience this regularly. I have found that leaving these larger notebooks open in chrome can cause lag to grow worse over time. Sometimes I can bring lag back down to a manageable level by closing the tab completely and loading the notebook from a new tab. Clearing output does not seem to help, so like your colleagues I’ll sometimes resort to splitting to a separate notebook.

I've seen many times that once notebooks grow up above a "small" size, rendering lags can happen. Running latest Chrome with a decent Intel i7 processor. For example, a notebook I am working on has around 35 paragraphs and is just 145k note.json (there are no big data tables - nothhing crazy), starts lagging quite a bit which doesn't help with UX. I've noticed paragraphs in HTML code can be burried 10 levels deep in DIV-DIV-... nesting. This could be the root cause? Browser might have hard time calculating all those nested CSS styles etc? I know some colleagues of mine start splitting notebooks into separate notebooks when they see this issue. Not sure if this is a known issue and if everybody else experience the same?
