Bug Description
Binary package hint: mc
Hello,
I was just copying about 20GB of data from the internal hard disk to an external one using mc (midnight commander). Using mc the desktop almost freezes, at least it takes 4 minutes until firefox starts. Thunderbird does not show any emails anymore. Mp3 playback becomes horribly interrupted. Switching between applications takes ages.
Using top on a text console, I saw that the %wa (iowait) entry in 'top' gets up to 85% to 90% percent. Stopping the data copy in mc restores the good behaviour of the desktop.
I then tried moving the data with mv. There is no iowait using mv, the desktop keeps responsive, only the %us (user space) entry in top shows some 80% percent, but that does not seem to slow down my desktop.
I think that mc should change it's behaviour when copying to that used by mv.

What's the FS on the external drive? Can you try newer packages to see whether the issue is resolved? The version of mc bundled with Hardy is really ancient and buggy.
