If you are getting 220Mbit/s on a speed tester it seems your connection
is not the problem. When my connection was limited to 100Mbit/s I was
getting HLShd download speeds up to 70 or 80Mbit/s, and they have
increased with the 200Mbit/s limit.
Speeds do vary enormously between CDNs and between modes and
occasionally some programmes are slower. In general I have found Akamai
to be faster than Limelight. I don't know about Bidi.
Where I am (and I think it may vary geographically)
hvfhd1 is Bidi
hvfhd2 is Limelight
hvfhd3 is Akamai
hlshd1 is Akamai
I see that the latest version of get_iplayer has a two-letter code to
identify the CDN without having to use --info --verbose
