I have very high bandwidth usage (all available bandwidth on my Windows computer), resulting in a hardly responding Octoprint webgui. This happens on multiple computers and with multiple browsers) on my Octoprint 1.3.11 running on Raspbian Buster on a RPi4 when opening the Octoprint webgui.
I'm not sure why this is happening.
As long as I don't open the WebGUI (through apps like OctoClient and OctoPod, the issue does not occur), there is no issue and OctoPrint runs fine. Also when opening the Webgui on iPad, iPhone or MacOS, there is no issue.
I have an (almost) identical Octoprint running with another printer, same hardware, same version, same plugins, and there the issue does not exist.
I saw some issues with high CPU usage, but I don't experience that.
My octoprint.log don't show anything strange, as far as my untrained eye can determine ;-). (see below)
In the logfile I started Octoprint, opened the Webgui and stopped Octoprint again.
