Public bug reported:
Binary package hint: nautilus
The software isn't necessarily *BROKEN*, but I think this still
qualifies as a bug:
So you plug 2 USB mass storage devices into the computer and mount them
both. You then open both of these devices in nautilus (each in it's own
window). Proceed to select a moderately large sum of data (eg. a movie,
or a few thousand songs) and copy it. Then Paste these files to the
other USB mass storage device. Nautilus will begin copying these files
(and the copy will work), but at an extremely slow rate.
I recently had this problem while making a copy of my music library
~80gB Nautilus told me it would take ~30 hours. This is not true; USB
2.0 does not transfer 1 gB/hour. But I let it go overnight and low and
behold, the next morning 20 hours remaining.
At this point I cancelled the transfer and copied the files to my
internal hard drive (which took about half an hour) and then copied the
files from my internal hard drive to the other USB device (which took
about 1 hour).
So I think that probably if there is unused space in the swap file,
nautilus should copy the files there as an intermediary holding area,
and then copy to the other drive. Or maybe these excessively slow speeds
actually are a bug. Thanks in advance for being so awesome!
