I have a file of hostnames I feed into queryperf that has 1233 names
from the hotwired.com domain, each repeated 150 times (plus an extra few
hostnames, don't ask).
BIND 9.2.0, dual PIII 600 Linux (debian woody), 2.4.17 kernel, with 384
megs of RAM:

I don't know about stability, as I use BIND 8 in production, but these
numbers should be sufficient for most sites.
This test was from across a wide area link, not localhost, so it travels
a real network.
Of course, BIND 8 on the same box gets better performance servig the
same data - but it's performance most sites don't need.
BIND 8.3.0 on the same box, queried from the same host as before:
