Public bug reported:
Binary package hint: nautilus
If copying a large amount of data on a relatively slow network
connection, it's impossible to see whether the copy is actually working
or has frozen. For example, showing "17.2GB of 30GB copied (220k/sec),
estimated time remaining 18 hours". If that copy process freezes, or the
network drops out, it's almost impossible to tell that it's done so; the
17.2GB will eventually change to 17.3GB, but you have to watch the thing
for 5-10 minutes to see that change. The progress bar will not move for
the same amount of time, and that's even harder to detect a change in
anyway. The average transfer speed also doesn't help; if you've had a
long sustained transfer at 220k/sec (12 hours, say, so far) and the
current speed is actually 6k/sec, the average won't change fast enough
to be detected.
Note: this is not a call for some sort of "fake progress indicator",
like a spinner, unless that spinner actually stops spinning if progress
stops. I had to resort to dropping to the terminal and "ls -lR"ing the
copying files to see if the size of one of them was incrementing (which
is very hard, because you don't know which one is currently being copied
and it may be in a heavily nested subfolder).
One obvious but user-hostile fix would be to show an actual byte count
for amount copied (18253611008 bytes of 30GB copied) because you can see
that changing. Another might be to change the "average speed counter" to
much much more heavily weight recent changes to the speed, but it
wouldn't be visible that that was actually the case and so would only
help people who knew that nautilus did this. A third way might be to
have a "details" expander which shows the name and byte count of the
current file being copied (at which point this becomes fix 1, show the
byte count, but hidden behind an expander).
