Description omega 2010-06-30 11:31:23 UTC

Version:           unspecified (using Devel) 
OS:                Linux

I've got a problem when I'm copying files between 2 partitions on same hdd:the cpu usage is always at 100% (dual core 2.53 ghz and 4 gb ram) and transfer decreases desktop responsiveness. 

NOTE: 
i have this problem with all version of kde.

Reproducible: Always

Steps to Reproduce:
copy files with dolphin

Hi there, I can't reproduce here, (svn r1157874 (KDE 4.5.62 (KDE 4.6 >= 20100729))) but marked this bug as "Bugs needing attention" so dolphin developers can double check it.

Thanks for the report, but I cannot reproduce this issue here too (4.5.2 + trunk). If I remember correctly some time ago there was an issue in Plasma, where showing the progress resulted in a high CPU load. Maybe you could try to turn off the plasma-progress indicator temporary...

It probably is a Linux kernel problem, see http://www.google.com/search?q=linux+bug+high+io+wait+time

i have this bug with kubuntu 11.06 (kde 4.6.0)

using cp, all works fine with low cpu usage but with dolphin, i have 100% cpu (dual core).
