<p>Hi Alex,</p>
<p>Have you tried on a separate physical server? To rule out the actual hardware as being the problem?</p>
<p>Is this some user grade PC with either onboard or external ethernet interface, or a proper server grade equipment? Age of equipment? What else does that machine do?</p>
<p>Cheers</p>

<br /> No, I actually upgraded from a 65/20mbit to a 165/35mbit recently,<br /> thinking it was too slow because it was happening at the slower speeds<br /> as well. I've also implemented some basic QoS to throttle outgoing<br /> smtp and prioritize DNS but it made no difference.<br /><br /> Thanks,<br /> Alex<br /> _______________________________________________<br /> Please visit <a href="https://lists.isc.org/mailman/listinfo/bind-users" target="_blank" rel="noreferrer">https://lists.isc.org/mailman/listinfo/bind-users</a> to unsubscribe from this list<br /><br /> bind-users mailing list<br /><a href="mailto:bind-users@lists.isc.org" rel="noreferrer">bind-users@lists.isc.org</a><br /><a href="https://lists.isc.org/mailman/listinfo/bind-users" target="_blank" rel="noreferrer">https://lists.isc.org/mailman/listinfo/bind-users</a></div>
