Bad 1.3.95 interactive performance

Hiho

With 1.3.95 and some kernels before (i don't know exactly when it started)
I notice unnecessary heavy swapping activity when the system is up some time.
Here comes an example scenario:
- boot the computer
- login into X (via xdm). This first time everything looks normal.
- logout
- Let the machine alone for some hours (in my case it is usually > 12h)
with nothing running except the usual cronjobs.
- login again and be surprised of the time it takes to get the desktop
(can be several minutes) and the neverending swapping activity of your
harddisc.

As long as the working set does not change everything is normal, but even
the smallest change results in heavy swapping (while the output of free
looks normal).

As nobody has written about this before, it seems that I'm the only one
having these problems. The only unusual detail of my configuration is that
I use the ncrBsd2Linux driver (version 1.8).
What can I do to fine out more about the nature of this problem (yes I will
try the normal ncr driver...) ?
