zvaral, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  Copying files to USB flash drive is extremely slow

Status in “linux” package in Ubuntu:
  Incomplete
Status in “linux” package in Fedora:
  Unknown
Status in openSUSE:
  Unknown

Bug description:
  Copying files from an internal hard drive to an external USB pandrive
  is slowing down during this process in Lucid Lynx alpha3 with all the
  updates until now. Also note that the copying speed is well below the
  standard rate for high-speed USB devices even in the initial state.

  As a first look this phenomenon is independent of the filesystem of
  the USB stick although some effect may be observed. I formatted it
  either ext3, ntfs or vfat the result was the same. Copying starts
  around 20-30 MB/sec transfer speed and around 300 MB copied materials
  the process is slowing down below 15 MB/sec and between 400-500 MB
  transfered data it is below 10 MB/sec. Reaching the 1GB amount of
  copied data the speed is only around 2 MB/sec. In case of using vfat
  file system the transfer speed may go below the 1MB/sec transfer speed
  at this stage.

  The number of the files I transfered from my hard drive to a 16GB USB
  pandrive were 350 with a total size of 5.4GB.

  In an other experiment (with ntfs usb partition) transferring only one
  large file having a size of 2.7GB took more than a hour (0.7 MB/sec in
  average)!
