Not sure if this is a known issue but I tried to load the site 3x in Firefox. Caused the tab to stop responding with a "Script is slowing down Firefox" error. Each time I had to close the tab. Opened the site in Chrome with no issue.
Yeah, the document loaded in the editor is nearly 1 MB by now. This document has grown over the last months. Over the last days there were 100 users concurrently typing in the document, some times pasting in 20k words, deleting it, pasting it in again … And Y.js (what we use) stores the whole history, and currently is blocking the main thread until the first state is downloaded and applied.
The collaborative editor seems seems to be struggling with the load test of visitors, combined with some people putting a lot of content into the editor--it looked like the entire Bee Movie script was in there.
Some people pasted whole books into the editor. In combination with more than 100 people using it concurrently, that’s not working that well. I limited the character count, it should be way more performant now.
