Slow typing text into fields

I'm finding typing into text boxes incredibly slow. This affects the names of dashboards & text boxes.
Browser doesn't appear to be doing anything. It can take 10-15 seconds for text to appear. I've resorted to writing everything in Notepad, then copying and pasting into Metabase.
Is this likely to be a server side problem? I've not done the deployment myself. I believe it's on Docker.

Hi @AndrewMBaines
Post "Diagnostic Info" from Admin > Troubleshooting.

It would appear that the solution is to post a question about it on here! Next time it happens, I'll post.

Happened again.
The whole UI froze, so I wasn't able to view the diagnostic until it started again:

@AndrewMBaines I don't understand what you mean about "until it started again" - what started?

I don't see anything in the logs indication anything, but I don't know if you are using http or https. If you are using http, then browsers only allow 4-6 connections per host, so that can make everything feel like it's unresponsive. You can still click around, but it will be waiting for connection.

I don't know if you are referring to this type of unresponsiveness:
https://github.com/metabase/metabase/issues/19683

Otherwise I think you need to record a video, so it is possible to understand better.

"until it started again" - I type into the box. Nothing appears. Clicking elsewhere does nothing. Text appears in the box, rest of UI now works.
It does feel like 19683, just more widespread.
