Mid-size notebooks lag in browser rendering / responding to simple navigation requests.
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?
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.

Thanks for sharing the experience.
If you can file an issue and attach a notebook file (with important information removed), it'll be extremly useful to enable any developer reproduce this issue and try optimize the performance.

Attached heap dump and records js memory allocations for a 10 minute period of time - hope it helps to identify the root cause.
I currently can't publically share theat particular notbook without significantly dropping many pieces there, but I
think that's applicable to any notebooks when they're over a certain size ( I mentioned that one was 35 paragraphs).
Although it may take hours to few days for that memory leak to accumulate enough when it starts affecting UX with significant lags.
