Forward it to the least busy server ;)

Recursive resolvers or authoritative?

The protocol itself has a number of "load balancing features",
but if your handing out client infomation via DHCP you might
check if DNS server IPs are always handed out in the same order,
and fiddle with DHCP to make it more even.
