Original GitHub issue: https://github.com/netbirdio/netbird/issues/4602

Describe the problem

When i add ~1000 resources to my network to route them trough specific peer i got high CPU load on peer where this resources was accessible. Alse there is blank "Networks" GUI window. I think there is some processing of resources occured on peer and it's load my CPU.

To Reproduce

Steps to reproduce the behavior:

Add large amount of resources to network
Send them to some peer
See high CPU load
See blank network window

Expected behavior

App works properly and normal CPU usage

Are you using NetBird Cloud?

Selfhosted netbird

NetBird version

0.59.3

Is any other VPN software installed?

No

Is there a some limit of resources count to work with them smoothly?
I try to send traffic to all of these resources to simulate domain-specific split tunneling VPN behavior with netbird app.
