No. And as mentioned before this is a Solaris 11 system, so /etc/system is
(mostly) irrelevant, as the IP settings are all done with ipadm now.

That, as well as the script and examples you provided, won't help me a lot,
as I am looking at UDP receive buffer overflows, not TCP.
I have set udp_max_buf to 4MB now and udp_send_buf & udp_recv_buf to 2MB
each, then restarted BIND.
It seems to be working better now as I don't see that much receive buffer
However, the initial question still stands. How can I reconfigure BIND to
pick up the data faster from the receive buffer ?

Yes, of course.
