desktop unresponsive during file copy


Whenever I copy files around on local disk or over nfs, my desktop becomes overly unresponsive. During the copy, it takes 10-30 seconds to open a tab in firefox, switch application windows or open konsole. This is a relatively new machine with a quad core cpu and 4GB ram, and I feel it should allow me to use graphical applications while copying files..

I have the same behavior using KDE in Slackware 12.2 and 13.0. Always had, but today I feel the need to scratch the itch. The system is not swapping to disk, in fact swap isn't touched at all. There are no processes worth mentioning other than cp and some generic desktop apps like firefox / thunderbird. I have no idea why it's slowing down so much, or where I should look for problems.

Any ideas?

cp is very CPU-intensive and will 'take over' all the spare cycles available. From the command-line you could use 'nice' to make it be less of a 'hog', but that won't help you with konqueror or whatever other filer, which use the same underlying library calls as cp.
