Here is a very quick perf comparison between three revisions of bind,
all compiled "stock" as the source shipped - in particular with -g. The
system is an hp visualize j5000 with two 440 MHz PA-8500 CPUs. In the
case of BIND 8 one instance of named was running and it was run out to
saturation of one CPU, with theother CPU basically idle. In the case of
BIND 9, named was explicitly told that there were two CPUs and they were
both run out to rather close to saturation with virtually all the time
in user mode.

b3 does indeed have a nice big boost in perf and increases single
instance named9 scaling from 0.62X to 0.89X of named8 on a two CPU
system. I hope to have some time to coerce the bits into compiling with
something other than -g and recreate more of the data from:
