Its *NOT* congestion, if it was congestion then *everything* would be slow
This is not true, you do not understand how the internet works if you believe all traffic is routed identically.
When you use the VPN, then yes all your traffic is routed via the VPN, and that route is likely not congested.
Your speedtests show very very clear congestion and your ISP is known for congestion widely.
Read the traffic management document published:
http://www.vodafone.co.uk/cs/groups/public/documents...
NO traffic is managed. They cannot lie about this... It is documented and formally captured.
1. You've linked me to the mobile traffic terms, completly different, even ofcom treat it differently.
2. I have access to several hundred hosted servers within microsoftcloud and google's cloud, a file download from these performs slower than if I VPN to the same server and download the same file, both the route there and the route back is identical as I own both ends and therefore can see the route traffic takes in each direction, I hope to have a spare server that i can do a wireshark capture to full analyse after the xmas break. Equally I can bouce my traffic off over 100 different UK VPN servers using 73 different routes, all demonstrate the same issue. Encrypted VPN traffic always performs at a better speed to the any download source sampled than a direct connection.
My speed test does not show congestion, if there was, then all tests would show a throughput hit, my speed test clearly shows there isn't congestion as I can obtain maximum throughput.
All ISP's employ traffic management, it would be iresponsible for them not too - this allows them to keep the network running if/when they have a major fault affecting their network, in these cases they can apply QOS to ensure that specific traffic can get through the congestion.
The question is - at what point does Vodafone move from deploying their solution (which I am sure they currently are) in order to protect their network to the stage of just leaving it deployed as it means they don't need to invest in the backend infrastructure to support their growth and their real bandwidth needs.
Finally - back to my point - i get less than 1MB/sec for *any* nntp traffic no matter where its hosted, compared with full 8MB/sec when hidden behind a vpn even a VPN to the same nntp server (so highly likely to be indentical router there and back as non VPN traffic) - that is not congestion, its not bad luck, its not the direction of the wind, it is only that speed for 1 reason, and that is that it has been prioritised much lower than all other traffic.
