OK. It looks like the numbers displayed in MDMA are incorrect. When tracing connection on terminal, getting the following:
The last two numbers show assigned QOS:
downlink 001E8480 = 2,000,000Bps = 16,000,000bps
uplink__ 00107AC0 = 1,080,000Bps = 8,640,000bps
It is consistent what MDMA is displaying (my first post messed up Mbps)
These numbers never change during downloading, there are assigned during connetion phase. So it is 16Mbps (instead of 21Mbps) and 8.6Mbps. I remember it was displaying 21Mbps previously.
BTW, This latest mdma beta is broken for /hexprofiles option. Older version shows hex data as above.
