Public bug reported:

Binary package hint: kdebase

I'm using kubuntu karmic 64 bit, with ext4 and a encrypted home. (ecryptfs)
When I copy, much files using dolphin (kio_file), the computer becomes (unusable) very slow. 
When I copy, much files using command line (cp), i don't have any problem. 

When i compare the copy speed between  cp and kio_file, cp is much faster. 
When I compare the cpu usage between  cp and kio_file, kio_file uses much more cpu. (wa: 80% in top)

The only difference, i can think about is that, kio_file constantly updates the status of the copy proces. 
I have tried this in ubuntu using nautilus (gvfs), and this works normally.

I think this has a high priority because, it makes the computer almost
unusable during a copy proces.
