Would you consider sending metrics to our public metronome server [1]<br>
so we understand what's the limiting factor during your tests? You only<br>
need to add a line like this one to your dnsdist configuration:<br>
<br>
carbonServer("<a href="http://37.252.122.50:2003" rel="noreferrer" target="_blank">37.252.122.50:2003</a>",<br>
"put-the-name-you-want-to-display-here", 5)<br>
<br>
This will only send some metrics without any private information and is<br>
very useful to understand where the bottleneck may be.<br>
