Really slow extracting of 'larger' packages with dpkg

[michaaa62]

Hi siducers,
with the newest siduction install of siduction 13.2.0 December - kde - (201312310241) i am experiencing some very slow extraction of large packages like kernel-image or kernel-header, as well as packages for localisation.
The system is fully dist-upgraded and works just fine, but the all the apt-get installs seem to stall for no obvious reason due to dpkg.
There is no evidence in top memory- or cpu-wise.(I used top instead of htop to copy the line, the basic output is the same)[size=78%] [/size]

Here is a typical output with time command attached, dpkg killed from another shell

Since nobody else complained (or i did not find it) i am thinking it might be my hardware... It might not be damaged, but might lack modules or firmware, because even heavy stuff like Windows7 in virtualbox or internet browsing with a couple of tabs even in many different browsers at the same time works just fine. Also extracting files or folders from different formats in Ark runs just fine.


The system runs on a SSD, but is encrypted using LUKS. I also tested this behaviour before with other flavours of this release on two earlier installs on encrypted systems as well on unencrypted systems. Same misbehaviour of apt-get on all of them.

encryption needs power ....

maybe a bug in debian may help
