I raised on kubuntu channel on irc and pepole there say " The 'problem' you have is that the CPU is waiting for IO. In the meantime it does nothing else. It's just waiting."

From your conversations did you find a solution or what is happening with this problem? Is it a bug I guess?

if external usb has ext4 filesystem there is not problem but if external usb has fat32 or ntfs problem still here . in first case i test 4 times and i don't see freezing and lag . i said on kubuntu channel this problem only is on my laptop . my PC haven't any freezing or lag during copy file . becuse all user around me use windows and usb storege ( fat32 or NTFS ) i can't use usb storege with ext4 filesystem becuse windows can't work with filesystem .

all ntfs or fat32 usb storage have problem.
