Bug Description
When a gateway with many Routers fails over to another, the failover is really slow and takes multiple minutes (adding roughly 1 or 2 addresses per second).
This can already be observed in the sync function. The function needs 350s to run. On the Gateway are 545 addresses bound. I did not remove any addresses, routes or rules before profiling the sync. As far as I can tell the most time is spent adding the ip route to the linux kernel. Would batching it improve things?
I attached my findings. The profiling was done with cProfile.
