Wouldn't it help, if you simply install a caching-only Bind on the DHCP-server who is only listening to 127.0.0.1? At least for the updates the dhcpd would get his answer instantly and the time consuming work is done by the local Bind asynchronously. For normal lookups it would of course only help if the answer is in the cache already. 
Looks like an easy workaround to me.
