per the man page
You could check the syslog, or use rndc:
vimes# /usr/local/sbin/rndc status
version: 9.7.1-P2
CPUs found: 1
worker threads: 1
...
2) What is the preferred way to determine "named" utilization ?
Are there measurable impacts to Query response not reflected in CPU load,
Memory or IO?
Not sure what you're after. Parameters to measure? Latency / response time?

Thx for the response..
I had forgot about the simple rndc solution..
We are having a discussion to determine if disabling query logging
improves DNS response time, when you have a machine that is under 10%
CPU utilization, I was looking to measure query times with and without
query logging..
I know Disk I/O would have a an impact but I feel it would be very little.
One party thinks that disabling query logging will give enormous
performance gains, while 30% is a lot.. IMHO it is very negligible in
CPU cycles when the named process only is taking up > 10% CPU..
and less than 10% in RAM...
Just looking for any suggested tests..
Thx
Charles
