Daniel, what do you see the load as? I see 4.6% CPU usage (100%
possible - 95.4% idle).<br>
<br>
I'm not sure which versions of BIND you were using on RHEL5, but the
newer versions do tend to use more CPU usage (I'll assume due to new
features, patches, etc in the BIND code).<br>

<div>We recently upgraded one of our DNS servers to RHEL 6. The
other two servers are running RHEL 5. The new system is
showing much higher CPU load than the other two (RHEL 5
machines sit around 11-15%). I am not sure if this is related
to the OS versions or something else. The build procedure for
the new system is completely different than before which could
also be the cause. Any ideas why this could be happening?<br>
