Copy/move between shares is sloooooooooooow...
I have SSH'd into my 316 and am doing cp and mv's... trying to move a bunch of data from one share to another (/data/share1 to /data/share2). It's slow. Like, really slow (maybe 90 seconds per GB)...

For posterity, the post from that thread reads:
Seriously? Really?!
So which folder should I put my downloads into? Transmission downloads to the /data/Downloads/ share on my system.
Now I have to move all files using an SSH terminal? All because I am using the /data/Videos /data/Music /data/Pictures shares that were there out of the box...?
On the NV+, I could of course map to /c/ and use this to move between shares. I had assumed this was the case with the 104 - simply map to /data/
How can it be acceptable that ordinary move operations are not possible on this device? What is being done to address this? Aside from forcing users to use a single share? The fact that BTRFS has this limitation is irrelevant - I need to be able to move large files without coping them...!

A direct consequence is that moving files from one share to another is done as a copy/delete - the same as moving files between two disks on a PC.
Well, not exactly. You can "instantly" copy files around between subvolumes using cp --reflink, and then remove the original. So, to move a file from the Backup share to the Documents share, you could do:
# cp -a --reflink /data/Backup/file /data/Documents/
# rm /data/Backup/file
