Need to improve named performance

Hello Alan -

Currently I'm not using query logging, it's not in my options at all. 
Are you saying that named logging by syslog into /var/log/messages is 
controlled by named.conf? Seems unlikely, I'd think it would be a 
function of syslog.conf. I'm trying to learn more about it but I'm 
swamped this am, just thought I'd post here to see if anyone knows a 
quick way to exclude named from the syslog completely.

I think the simplest thing would just be to have an exclusion in the syslog config for named. I confess some general ignorance, so perhaps you know the directive for that?
