I just wanted to add, the "few more ms delay" - is actually more like the following:
---

I wouldn't consider that just "a few more". This is just Ping and doesn't consider time in protocols where there's also the additional trip from the server to the user.

I don't understand why this is a problem - a few more ms delay on a reliable fibre network will not adversely affect DNS lookups.
This may not be entirely true for streaming services, especially voip telephony. While a phone or its server is looking up a host name in DNS, there will likely be no audio heard on the connection. The connection will appear to have gone dead or have a momentary dropout until the DNS responds. And, the longer the delay in getting that DNS response, the longer will be that dropout period of time.
For streaming video, you will get no dropout, but you will see a frame freeze.
For typical tcp services, such as web, there will be a slightly longer response time when changing pages. Of course, smtp will not show anything.
