You didn't say what you mean by latest build.  The latest BIND 8 build
is 8.3.1.  Is that what you are running?

You also did not give examples of the problems you are encountering.
Why not post some examples of problems so that people can
help you? Define proper performance and what should be the
proper response time for a query? What kind of query?
