Slow Gateway Page Load with Immediate FUOTA & Multicast API Calls

Viewed 34

ChirpStack version: v4.14.1

I’m experiencing significant UI lag and slow loading on the Gateways page when managing a large deployment. On page load, the web UI fires multiple API calls immediately, including:

api.FuotaService/ListDeployments
api.MulticastGroupService/List

The page displays a loader to hide the UI while these calls are happening, but with so many applications and gateways, it takes a long time for the page to become responsive. This seems to be due to:

The UI fetching all FUOTA deployments and multicast groups on initial load.Continuous polling that adds additional load after the initial API calls.
