absolugtely correct. My main grief wrt. responsiveness of desktop
systems is when the VM decides to grow the cache at the cost of pushing
parts of KDE into swap. As a result, "activating" windows that I
haven't touched for some time takes noticeable delays, which ruins the

My best setup for this is to have lots of memory and disable swap (and
live with the consequences- eg. triggering the OOM killer).

Admittedly, things seem to be much better now than six month ago.
