Today I had a very high system load because I used many applications at the same time (VirtualBox, totem, firefox,...). The load was so high, that the system almost didn't react anymore. Then I killed VirtualBox and the system became a bit faster, however it was terrible slow compared to the usual behaviour though I killed all large applications. After a reboot I got the message:
/dev/mapper/cryptsetup1 is not ready yet or not present, slow system
However the system works but very very slow.
I tried to disable and reenable encrypted swap as described here: http://www.logilab.org/29155
Now the error message is missing but the system is still very very slow.
Any idea how to fix this?
