[Bug 582390] Re: File transfers to USB devices constantly SLOWS down on large files > 200MB!

apport information

** Description changed:

  I know that this BUG is killing MANY people for a looooong period of
  time. But still, the bug report for 197762 was kind of closed: no more
  comments and the advice that this is a hardware-dependent issue!

  Well, I disagree! There are many people using Ubuntu that have that
  problem - but nobody seems to care!!

  The symptom: when copying a file with several hundred MB in size (or
  larger) - the copy process starts fast (in my case >30MB/s) - but then,
  it dramatically slows down and gets slower and slower and slower!! The
  system load rises to levels > 6 (and NOTHING else is happening on the
  system at all!!). The copy process will finally come to a (successful)
  end - but it takes a long time: 2 GB copied in more than one hour!!

  Now: it might be "hardware-dependent" but definitely NOT a hardware
  failure! The same system under Windows: no problems at all!

  What I got: a Dell Latitude D830 with a Core2 Duo, 4GB of RAM - running the 64bit version of Ubuntu.
  This bug has been there for many Ubuntu versions: the first I started with was 8.04 - same issue!!!

  WOULD SOMEONE PLEASE TRY TO HELP???
  Thanks!!!
