Wow, that's amazing. I never got much above 60 Mbps even with hlshd.
Are you using WiFi? That will slow your connection.
No, the only thing I use wifi for is my phones. I'm old school,
everything is hard wired Gigabit with a mix of Cat5/5e cables. I get 220

Since posting, I tried hvfhd2 and got 50 Mbps initially, but a while
later it was maxing out at around 25 Mbps. I do most of my downloading
overnight, so it's not crucial. I've rescheduled the timing of my
download batch files and I'm forcing hvfhd2 for now, so I'll keep an eye
on transfer speeds.
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
