I will try with different schedulers tonight.

It is not only Thunderbird, which does not have much cpu usage for itself. This laggy behaviour is also noticible by just switching some terminal windows (I use gnome-terminal, again, it for itself does not cause much cpu usage nor disk i/o), minimizing them and so on.

If I set the priority of make -j3 to -n19, the problem vanishes, so I expected the scheduler to be to blame.

Again, thank you all for your efforts :-)
