Bind 9 is slow? Please help

I am repeating my issue as I am in need of quick help.

I have installed bind 9.3.1 on Solaris 8 (IPv6 on Solaris is not
enabled) , it was taking long time to resolve the names. As per some
suggestion on this list I started named with -4 option and it solved the
problem, now I have following two questions.

1- Is this the right solution of this problem? Any disadvantages of
using -4 option?

2- If I recompile the bind with --disable-Ipv6, will it help?

Many Thanks,

Hi Jim
First of all thank you very much for your response. I am sure it is not
enabled, even I have verified after your suggestion. I saw Mark Andrews
of ISC also suggesting that it is a known issue and one of the
workaround is running "named -4", he wrote that it will be fixed in
9.3.1 but I am using 9.3.1 and still the same problem.

Is there any disadvantage of running named -4 until I found a solution?

Mark Andrews! Would you please help?

Well IPv6 must have been enabled somehow. Check your OS documentation.
Maybe you installed a patch or something and that switched IPv6 on.
As for the permanent solution, consult a Solaris expert. You could
contact Sun support or ask in one of the many newsgroups or mailing
lists that deal with Solaris administration. bind-users isn't one of
them. Feeding "Disable IPv6 Solaris" into your favourite search engine
could well point you in the right direction.
