pfSense DHCP / DNS performance

pfSense... Anyone have much experience with the new Kea DHCP server?

I'm using 2.7.2 (Community Edition) on a fairly good Celeron based system that's not heavily loaded, but I have 7 network segments (VLANs and physical interfaces), so I have 7 DHCP pools / configs and just adding 1 more static reservation can cause a significant delay when reloading the service and because I register static reservations in DNS, I can lose comms.

Would Kea fix this?
