<p>Hi all,</p>
<p> </p>
<p>There is also a control plane performance issue when we try to catch on the spec of typical AWS limit (200 subnets per router). When a router with 200 subnets is scheduled on a new host, a 30s delay is watched when all data plane setup is finished.</p>

<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">We have started to test Dragonflow [1] data plane L3 performance and was wondering</p>
</div>
<div>
<p class="MsoNormal">if there is any results and scenarios published for the current Neutron DVR</p>
</div>
<div>
<p class="MsoNormal">that we can compare and learn the scenarios to test.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">We mostly want to validate and understand if our results are accurate and also join the</p>
</div>
<div>
<p class="MsoNormal">community in defining base standards and scenarios to test any solution out there.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">For that we also plan to join and contribute to openstack-performance [2] efforts which to me</p>

<p class="MsoNormal">are really important.</p>
