It appears that peer-group changes are extremely slow; a single change to a peer group takes in excess of 1 minute. This server has no RADIUS configured, and it is a bare metal with 2x Xeon Silver 4210, so it's not a resource issue.

It's difficult to show how long it's taking, but the following two commands took about a minute and a half each:
```
vyos@cr01a-vyos# set peer-group BACKBONE address-family ipv4-unicast route-map export BGP-BACKBONE-OUT
[edit protocols bgp 4242420670]
vyos@cr01a-vyos# set peer-group BACKBONEv6 address-family ipv6-unicast route-map export BGP-BACKBONE-OUT
[edit protocols bgp 4242420670]
