copying a lot of data to an usb drive slows down dramatically

[Vreemde eend]

Binary package hint: nautilus

When copy a lot of data (>2Gb) to an external drive, it starts fast (>20MB/s), but it immediately starts slowing down (<2MB/s). It makes no diferrence whether it's one big file or a lot of small files. I get the same problem copying data with cp, rsync and Nautilus. I had the problem with bot an ext4 formatted drive as a hfs+ non journaled formatted drive (source in both occasions ext4)

if you get the same problem with copy, rsync or whichever other tool, well that's not a nautilus issue. the bug needs to be reassigned.

[Mohamed Amine Ilidrissi (ilidrissi.amine)]

This should be a general kernel issue. Please correct if you disagree.
Anyway, does this bug still occur to you? Can you test Maverick to see if the issue is still not fixed?
