      Hi!

      My NSLU2 suddenly turned very slow when accessing it via network - I
      did not do any changes to the configuration of my network or the NSLU2
      itself. Copying a 100 MB file to or from the NSLU2 takes about 10
      minutes - this was a lot faster a few weeks ago.

      Here is what I did so far to track down possible error causes:
      - Connect the external HDD of the NSLU2 directly to my workstation and
      copy files directly. Worked with full speed.
      - Changed the network cable to the NSLU2 - no speed improvements.
      - Connected the NSLU2 to another switch - no speed improvements.
      - Copyied files directly from one workstation to another via network.
      Worked with full speed.
      - Restarted the NSLU2. No improvements.

      Do you have any suggestions why my NSLU2 could have turned into a
      snail over night?

      Here is a dump of ps and free:
