Thanks for help! When I monitor with htop there are no processes above
5% during unpacking/copying. I have fairly fast hardware ( Intel Core
i7-2600, 8 GB DDR3, samsung 7200 rpm), which shouldn't be the problem
especially since the same hardware works fine in Funtoo. I suspect
that the problem is that Debian (kernel) configuration is optimized
for servers not desktop. I'm interested to learn which (kernel)
options need to be changed in order to increase performance in Debian.
I have no interesting messages in the logs, is there additional
information I can provide?

Which kernel are you using? 'uname -r'
Which desktop system are you using?

Hi,

Are you using Nepomuk, beagled or another similar daemon? those
"guys" can affect your system desktop performance.
As GlenB says kernel and desktop version are a very useful information too

Best Regards

Does top show something unusual?

I can confirm similar, not as extreme as it seems to be for you, with
Ubuntu Maverick, Debian stable and testing. For Ubuntu Maverick it might
be even more evil as for you. There something uses 90% CPU, can't
remember the name and won't reboot and there's a zombie for every GNOME
session.

What tool are you using for copying and unpacking? Command line, GUI
browser (nautilus, dolphin), Midnight Commander...? Different tools can
make a difference here.

And what kind of copy (internal hard disk copy, disk to disk, disk to
network share...) and what kind of unpacking?

Greetings,
