I have a quite large Dashoard (13 tabs, full of controls) and it is very slow upon starting/loading. After then, operations are normal. I was watching at the "Network" tab in the browser's developer windows and I noticed that it took more than 7 seconds to load this css: CSS for https://www.<my-do…

Dashboard is heavy. And there's nothing you can do about it. I haven't had time to stress test the new dashboard 2.0 but as technology behind it is modern I do believe there is improvements. But if performance is important, one and only option is to make it from scratch.

You said you see 'CSS generated in 7750ms' in the Network tab in the browser tools, but that should be in the Console tab. It would be interesting to see what the Network tab does show in case the page fetch is part of the issue. I have a somewhat smaller dashboard running on a pi 3 and the equiva…

[image] Colin: What does the command top in the Pi show? During Dashboard load, top shows over 100% for node

And the network tab in the browser? Also what does top show when not loading the dashboard? I would like to see the memory stuff as well as the top few lines of processes please.
