PMM Monitoring 1000 Nodes, Few Dashboards have huge load times, Unresponsive UI

As part of the activity, we planned to document all the performance concerns we observed on a PMM-Server monitoring 1000 Services and Nodes.

We Observed

1) Home Dashboard

2) Env. Summary Dashboard

3) Prometheus Exporters Overview dashboard

Have really high Load times, more than 1 mins, mostly all the requests are stuck with the browser complaining about unresponsive UI.

User Impact: PMM Server monitoring many nodes/services has an unresponsive Home Dashboard UI, making it impossible to use the application.
