Same results, cli copy takes about 7.5 seconds (thats around 40MB/s), and
gui copy says it runs at 7.8 MB/s.
This could be the normal behaviour I could expect, gui is slower as it has to
update progress bars, move flying sheets, or even does a sync from time to
time.

The misbehaviour I see is the other way aroung, FUSE/GVFS is fast from GUI
and slow from CLI. And, the best, why are there any difference ???
