Thanks for the great feedback! We’re investing heavily in improving performance right now, and understand how important this is.
We announced a few improvements for loading docs in November, but that was only a start – we’ve been busy since and are looking forward to rolling out and sharing more updates soon. And we’re planning continued significant investments in performance in the upcoming year.
(One of the changes mentioned in that post was moving document content to CDNs so they’ll load from a location closer to you)
