speeding up distributed multihead (xdmx)

[Joshua Marshall]

Hello all,

This summer I've been charged with updating my university's display wall.
It looks like the software features of X11 eclipse those of DisplayCluster,
but in speaking with the DisplayCluster author, it _actually works_.  In
particular, the performance over 16 screens was wholly unacceptable and
traced it to a part of the server which serializes a nondescript something.

Now, does anybody know what he is referring to, if the performance issues
persist, and how hard it might be to fix them?
