Lazily instantiate codemirror instances #1615
By taking advantage of the fact that a user can not interact
For small notebooks this change has a limited impact, however for large
Initial setup work
I did some follow up time measurements on my computer (these numbers will be highly variable depending on the system)
Time from clicking on the recent notebook item on the dashboard until being able to interact with the first codecell
Thanks, that's a fantastic improvement in performance.
However, I can see the code cells instantiating as I scroll, which is pretty annoying.
Instead of starting them out as unstyled text, can you initialize them to the right font size
