Hi @RehabMan,
Attached is the files you ask for problem reporting.
* ISSUE:
All the USB 3.0 'SS' ports are operating at slow speed
With USB 3.0 HDD enclosure, its 70mb / sec in linux and windows
...Here on MacOS its 14 MB/sec
BTW I only have this one USB 3.0 device to test with. So unfortunately cannot cross-check with other USB devices. But from reading PierAlpha’s blog post comments theres other guys reporting the same issue. It happens on recent version(s) of Sierra, since September 2016.

[EDIT] Noticed that if you have browser text zoomed, then these links do not go to the correct places in the comments. So make sure your 'browser zoom' is set to 100%. You might also have to reload the page again too (CMD+L, Enter).

It seems they didn’t find any solution yet. So what do you think about it @RehabMan?
You need to follow the guide here...
You have 20 ports under XHC. Must get at or under 15.
