Honestly, I think that a design spec of getting DNS responses in 3ms
across the board is unrealistic. My initial MX query for litc.ly
<http://litc.ly> took 367ms:____

Like many poorly written / articulated SLAs, the devil is in the details.
I could happily read this as the server / service must respond within
3ms. The OP mentioned VIP, so this could be for auth DNS, in which case
responding to a query within 3ms is trivial...
no it is not - at least not if there is an internet connection between
customer and dns server since you hardly get even a 3 ms ping time
on the server itself yes
frankly even in a local network you end with ;; Query time: 1 msec for a
"dig NS" and that a nameserver can respond on localhost below that is
completly worthless
however, since the OP even don't know if he requires a recursive
resolver or a authoritative server any discussion is pointless unless
the OP is completly re-written based on
