I'm sorry I don't understand. Please provide a clear use case.
I've never heard of "factory default on a large server".  

Our company is developing a core-router that is supposed to support thousands
of links, both physical and virtual. (e.g. loopbacks, tunnels, vrfs, etc)

At times we are required to configure massive amounts of interfaces at once,
such as when a factory reset is performed on the router (causing a deletion
of all links), a configuration is restored after an upgrade,
or really whenever the system reboots.

The significant detail in Lahav's benchmark is not "deleting 10K loopbacks",
it's "deleting 10K interfaces", which *is* a good representation of what we're
trying to do.

Alright, no fundamental objections here if you do in fact need this.
Please address the review comments.
