With the capacity of our servers being in the 18 Gbps range I would say max dns answers should be between 2-4 unless volumes expected are > 250 Gbps. I think 2 or 3 would be a good starting point for most services.

I opened a PR (1611<https://github.com/apache/incubator-trafficcontrol/pull/1611><https://github.com/apache/incubator-trafficcontrol/pull/1611%3e>) to change the default from 0 to 5 which is hopefully a sensible value for most deployments. If this doesn’t seem like a sensible default please respond with alternatives. Thanks, Dylan
