Default Re: Big Wall display (more than 10kpixels) - Slowdown problems.

I have a few questions:
0) How are you tying all of the X screens together between these systems? Are you using Framelock cards?
1) It is fully expected that there will be a non-trivial performance loss when using the Composite extension (especially on large desktops, such as you are using). This is because using a compositor requires that everything be first rendered off screen before getting composited back onto the visible desktop (effectively twice as much rendering). Do the performance problems persist if you're not using the Composite extension?
2) You stated that every 3D application crashes. Is this only when using more than 3 nodes or regardless of the number of nodes?
