All of these are shortcomings / the hard reality of either TCP or UDP and the nord service itself.
I don't fully agree. I always had excellent speed with NordVPN using UDP, it's only with TCP protocol there's been a problem.
You don't have to agree, I wasn't stating an opinion; but rather facts concerning actual shortcomings of the protocols themselves.
UDP gets its speed from the fact it doesn't care about the data getting transmitted. Blast a datagram to the void, and hope it makes it. Worst case; we lose a couple of frames of streaming video, or maybe voice drops out on your skype call. There's a reason it's got the nickname
Unreliable
Data
Protocol.
TCP-based VPN is so horrifically slow, because you're encapsulating a TCP stream (e.g.
https://example.com) in another TCP stream; and if either mucks with packet orders or needs resends or anything, the whole segment gets thrown away and resent from the start.
