How can i improve my recursive resolver speed.
I wonder if you have some kind of networking misconfiguration which
results in timeouts while BIND is waiting for responses. Perhaps you
will learn more about what is happening if you look at the network
traffic using a tool such as Wireshark.

Great minds think alike... :)

For the purposes of comparison you can always try a public service:
laptop3:~$ >>> dig @8.8.8.8 lists.isc.org
; <<>> DiG 9.10.3-P4-Debian <<>> @8.8.8.8 lists.isc.org
; (1 server found)

Seems to me that 62ms is very respectable. If you have problems with
your own service you can probably use a different one, if only until
such time as you can fix your own (and if indeed it needs to be fixed).
