As with everything, it depends.
A video stream and general web browsing can easily take a 300ms delay no issue, but voice and gaming will have issues.
Voice is fine for upto 150ms according to the IEEE.
Does the 300ms include dns latency?
Not for the duration of the stream, only for initial page load
DNS is only used initially on first load, after that the connection is made via IP and DNS isn't used.
Yes, but if you hit a company doing DNS based load balancing, DNS is going to return an IP that's near to your DNS server which may not be near your device. That's going to add to the latency.
Yeh but assuming you are in the approximate same geo as you pihole it should be the same now if you deploy your pihole across continents then i would say you should really reconsider your decision.
Gotta downvote for misinformation here.
A requested video stream and web browsing is not bidirectional, and the 300ms you use as an example is not the roundtrip of traffic in that case, but also the response time of the application server.
The 150ms jitter for real-time voice/video and gaming netcode is streaming bidirectional , and that number is what most users say is not noticeable in real-time communication. You can obviously have more and still have a stable stream up to what the codec will tolerate.
HLS is a bidirectional protocol though - the system's total network latency affects how quickly it can change to a new bitrate stream as conditions improve or degrade. And despite the name, it's not just limited to live content. You can use this to deliver fixed-length content
