Thanks, as you know from the ticket I posted, without this fixed my CloudDrive is pretty much unusable for my intentions.
I think @steffenmand's guess is most likely the correct one in that CloudDrive thinks it is still getting 1-2mb chunks as anything above auto for minimal download has the same chunk downloading over and over.
Hope Alex gets going on this soon as this seems like one of the most replied to threads in this forum.
Appreciate your efforts so far, this is a pretty slick piece of software.
