This is probably caused by the switch to using a built-in HLS/DASH
downloader, rather than FFmpeg.  I haven't looked at FFmpeg's download
code, but I would imagine it is multithreaded, downloading several HLS
chunks at once before reassembling them.  get_iplayer, on the other
hand, downloads chunks sequencially, one after the other, and as each
chunk is only 10 seconds long, there isn't time to really ramp up the
download speed.  I recommend filing this as an issue on the bug tracker
or posting about it on the forum, as it would greatly decrease download
times.
