Herewith, in what I hope is pleasant surprise, a preemptive gesture on
my own part: I agree with you.

Hey, I agree. I think there are too many eggs in that basket, and too
much code for a monolithic design. Further, I think having all 13 root
nameservers run BIND is friggin' nuts -- and that it would be so, even
if it weren't BIND8 that they're running.
I likewise think that the time for keeping all data in an in-memory
cache passed a decade ago. Vixie knows this from personal experience,
since adding the DNSSEC data to BIND9's cache has tended to explode the
RAM requirements to the point where even ISC's enormous primary DNS host
has a difficult time juggling all that data. I heard him admit this
during a lecture, a year or so back.
Also, we always suspected that the throughput of BIND (any version)
sucked, but recently have been seeing confirmation from competiting
products. Notably, MyDNS has proven to have an order of magnitude
better transction-handling capacity, despite being back-ended into a

But there's also the fact that he's willfully comparing it against one
of two monolithic-binary designs (Sendmail, Exim) rather than against
the two other common modular ones (Postfix, Courier). Apples, oranges
-- and both he and essentially all of his groupies know it.
Certainly, it could be coincidence. But, as Runyon said, that's not the
way to bet.
