We moved from RHEL5 9.8.3 to RHEL6 9.8.3, and saw no performance change. 
We then upgraded through various versions to 9.9.3 (still on RHEL6) and 
also saw no performance change.

I'm not sure what you mean by "does my named performance get any better" 
as it's fine now, but if you're asking whether CPU usage changes with 
that option, I'm afraid I'm not about to mess with our production DNS 
servers to answer a random mailing list query ;o)
