single-machine load balancing

[sschmidt at my-deja.com]

Strange question:  Does anyone have any experience running multiple
instances of named (bind 8.2.2-P3 is what I'm using) on a single SMP
machine?  I'm running into a bottleneck on one processor right now, as
the named process doesn't spawn clients for each query (reasonable).
Rather than assign additional machines to the task, I'd rather just run
multiple instances of named bound to different ports on the same
interface, thus utilizing the spare processor cycles I have on the
other processors in the box.

I've tried creating a separate config file for the "new" named process,
instructing it to use different directories, listen-on a different
port, use different channel names, and still end up with this type of
debug-on-hang:

ns_init(/etc/named2.conf)
Adding 64 template zones
evSetTimer(ctx 0x80d55f8, func 0x80607f4, uap 0, due

Any help is appreciated.
