Comparing local-network performance with "random" cross-internet traffic IMHO isn't very useful, because there is a wide range for internet latency.
My wired desktop gets DNS responses from 8.8.8.8 nearly as if it were in my network, in way under 10 ms, ping responses in 2 ms or so. Accessing websites hosted in e.g. Korea takes >100 ms.
Add a congested wireless connection somewhere (WLAN or mobile network) and you can add another few hundred ms. And neither cross-continent nor congested wireless latency is going to go away.
Perhaps I should have been more explicit - comparing local audio traffic to local web traffic, there's a heck of a lot of difference. That would be the stacks.
