Poor Performance bind 9.3

[Layer3guru]

I need some help on where to start troublshooting.

I have 1 xp client
1 2003 server Active Directory
Bind 9.3 on FreeBSD in chroot

If I point the xp client to the 2003 box dns is very snappy but if I point 
it to the bind box it is very slow and times out from time to time. Here is 
my conf file I have dhcp working and updating bind just great. Just trying 
to troubleshoot the slowness issue. This is a test lab of course. I am just 
not sure why one works great and the other sucks. I am trying to migrate a 
small company to bind but trying to test everything out in my lab first.
