This is very unusual in my experience. On a single CPU machine,
BIND-9 will typically be somewhat slower than BIND-8, but I believe
it more than makes up for that with a variety of other advantages.
In terms of the kinds of things that you'd be able to see externally,
you should not notice a major performance difference -- you'd only
see that if you were using tools to generate artificially high query
loads, and you compared the numbers returned by one machine against
I'm a little curious what the OS differences are between these
two machines, what the virtual memory configurations are, etc....
