Yes, I have read it. The failures Neil is seeing are not connected to the fact, that each DHCP agent receives full mapping.
So I'll reply his points:

1. https://bugs.launchpad.net/neutron/+bug/1453350 has nothing to do with amount of VMs/amount of DHCP agents. Distributed DHCP will not solve this problem.

2. Load on servers.
Distributed DHCP will make this problem worse. Especially coupled with DVR, which puts 2 additional agents per compute.
In fact it is much more complicated query to fetch ports on particular compute than to fetch ports belonging to a network.

The problems with server load should have been fixed by moving to separate state reports queue.
