Optimization grafana

My grafana has been set up, because the need to monitor about three hundred of the Item, each time the grafana open dashboard is very slow, there are any places to optimize it?.

You might want to splitt up the dashboard into more dashboards or collapse some rows. Grafana will not requests metrics from the backend for collapsed rows.

Oh, thank you. Can you say something more specific? I have about 120 monitoring items on my dashboard. It’s slow every time you open it. Can you help me?
