Original Pull Request: https://github.com/netbirdio/netbird/pull/4137

State: closed
Merged: Yes

Describe your changes

This change addresses an issue where BufferUpdateAccountPeers could trigger numerous concurrent executions of the expensive UpdateAccountPeers operation.

The new implementation debounces these calls, ensuring that a burst of updates results in a single, synchronized execution. To guarantee that no updates are missed from goroutines that exit early on TryLock, a timer (AfterFunc) schedules a final UpdateAccountPeers call after the last trigger, capturing the latest state.
