[sentinix-list] BIND

I'm looking for advice if anyone has configured BIND on their Sentinix
server.
I set up BIND as a secondary and seem to be having performance issues, also
the init script is missing...?
I created the conf file (copied from another Linux server on my DMZ, changed
options as necessary) then ran rndc-confgen It starts up and runs without
error, however from the client side it takes 3 or more seconds for a
response, other servers on the same segment don't have this issue. 
Could this be because the NIC is promiscuous?
Looking for help/experience...
Thanks,
Travis Albrecht
