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)
