What about zone configuration in BIND 8 and BIND 9? Is there any difference between the two ?

Thanks & Regards

I didn't notice anything like that when I last upgraded from BIND8 (back
in 2001 or so).

When that is said: what kind of hardware are you running it on? Single
CPU? Multiple cores? I've seen some fairly ancient performance comparisons
between BIND8 and BIND9 that claimed BIND8 performed best on a single-core
CPU only. And if I'm not mistaken, BIND9 had some less-than-optimal
threading back in those days, and performs much better now.

Is pure performance important to you? Will you be likely to even notice?
Also, BIND8 has been deprecated for almost 4 years now.
