Hey,<br>
Looking for someone to take a look at my question on
Ask. Never posted here before, and am running into
issues configuring HA OpenStack using Neutron DVR<br>
<br>
<a moz-do-not-send="true"

rel="noreferrer" target="_blank">https://ask.openstack.org/en/question/91489/why-is-liberty-neutron-dvr-so-slow/</a><br>
<br>
Any help would be much appreciated. I am at the
conference this week, will buy you a beer if you were
willing to help!<br>

Do you have properly configured MTU all over the path
(increase in all switch/host, or decrase on guest)<br>
If you have vxlan or gre tunnel, this can be your
bottleneck...<br>
