Hello. Sorry if OT, I think this perhaps should go to suse-admin list The key point is to remove 'stun' effect and launch application faster with minimum budget. Option 5 can be taken only if all 1-4 cannot solve the two problems.
Get a second machine and migrate some of the users to it. 8 users running X11 on a single PC at once is a bit much, IMO.
BTW, the reason for 'stun' effect I cannot understand. Why the machine 'stun'? When a user load a 500KB webpage, she is expecting to way a bit longer, she should wait for other users, she should get no more then 60% CPU resource and keep other people's console still usable but only slower.
i suspect that this is caused by resource locking issues in the shared libraries. i notice that when my g/f and i are both logged in to my machine (running 2 KDE sessions), apps like kmail seem to take notably longer to do anything at all. My *suspicion* (not backed up technically) is that it's a shared resource bottleneck somewhere in the KDE libs.
I am afraid the system resource is not assigned in a fair way.
It's not - 8 X11 sessions is too many, IMO.
I remember a long time ago I was sharing a Sparc desktop (using gnome) with several other people and we never had 'stun' problem, is sparc platform better on sharing?
Sparc is better at being "smooth" about concurrent logins, in my experience. e.g., a Sparc with 400MHz can out-perform a typical 1GHz PC when it comes to disk i/o. -- ----- stephan@s11n.net http://s11n.net "...pleasure is a grace and is not obedient to the commands of the will." -- Alan W. Watts
