As for testing -- should be able, but maybe not too fast. Dunno if you rememeber, but I had some probs w/links back around Feb 2-3 2017...and you asked for a wireshark trace that I sent on on the 3rd...then we both got distracted. (same list) I sometimes have a long cycle time...you too? :-) I could send the dump again... ;-) Seriously, I went back to using a single UID mount and that works around the problem, as in my case I have perms to read all of the links. I just recently tried it again -- and hit the same type of behavior.
