Very high refresh time

Hello everyone,

I have some dashboards to monitor the state of my routers. But those dashboards take a very long time to load, and then a very long time to refresh. For example, after waiting around 10 minutes for the dashboard to load, nothing happens. I came back after meals and it was loaded. Then the refresh of every panels can take up to 2-3 minutes…
I’m working with InfluxDB V1 and I don’t think I can optimize any more my different queries.

Any hint on how to reduce this time?

Best regards
