A few observations:
1. You don't say specifically which versions of BIND 8 or BIND 9
that are used. This information would be very helpful.
2. I assume that the BIND 9 tests were done with 9.1.2-REL or maybe
a release candidate for 9.1.3. I'd also be very interested to
see results with BIND 9.2.
3. I don't see any BIND 9 caching results for Solaris on a
class B network.
4. I don't see any BIND results at all for the authoritative
tests.
5. I am still not at all convinced that the caching nameservers
should be forwarding those results to another nameserver.
I believe that you should also try setting up the
caching nameservers to be falsely authoritative for the
parent domain and delegate the child (in which all queries
will be performed) to the other server, and caching the
results that are returned.
Also, I'm not at all convinced that dnsfilter is the proper query
tool, but then I don't know of anything better. Since I can't make
any alternative suggestions, I can't really consider this to be an
issue that you should try to address.
I eagerly await further testing results!
