I have noticed that my uibuilder webpage sometimes takes a really long time to refresh. Usually it refreshes within a second, but it then reverts to 10+ seconds after some time in use.
In the network tab of the console I can see a websocket that keeps increasing in time. It may have nothing to do with the lag, but I don't really understand the back-end at all, so thought it might indicate the nature of the issue...
In the Console this is what I'm seeing....
When I hit refresh I see this as it's trying to connect
