comment Why is moving files between btrfs subvolumes an expensive operation?
This doesn't answer your question, but you may be interested to know that from coreutils 8.24 (released July 3, 2015) onward, mv will try a reflink before falling back to a standard copy (changelog).

comment MemTest is returning large numbers of errors in Test 7, no matter what ram I use
sudo cp will set root as the owner of the copied file, so the chown is not necessary (but it was a good idea). Note, though, that sudo mv will not set root as the owner of the moved file. Also, instead of sudo chown root, you would usually want sudo chown root:root to set both the user and group ownerships to root.

comment MemTest is returning large numbers of errors in Test 7, no matter what ram I use
Hmm... I think gunzip is included by default. In any case, I'm not sure why that's not working, but we just want to get the Memtest86+ ISO into the /boot/images/ directory, so here's another way: Download the memtest86+-4.20.iso.gz file normally through your web browser, and open the directory containing it. Right click on the file and select 'Extract here'. Now run sudo cp /path/to/download/mt420.iso /boot/images/memtest86+-4.20.iso to copy the extracted file into the /boot/images/ directory. Then follow up with sudo update-grub2. Let me know if you run into problems.

comment What else can cause memtest failures?
This is a known bug in the Memtest86+ distributed with Ubuntu 12.10. See my answer to this duplicate question.
