But the single threaded results weren't as extreme as we see with Plusnet.
An LNS is a massively complicated device that probably has multiple 10Gigabit connections on the output side, and a few 40Gigabit connections on the other to the ISP core network.
The 10Gigabit connections to the 'tail' provider (e.g. BTwholesale/WBC, TalkTalk etc) has the added complexity of having to terminate a bunch of L2TP or PPP sessions. It also has to manage the traffic flow to these end user sessions so that they are not overloaded, which causes packet loss.
So sending 74mbps to you, 55mbps to me, and 68 to another customer, whilst coping with another few thousand at the same time, requires complicated software, and fast RAM storage.
Hence these things cost a fortune and if they go wrong it causes "fun" for all
