We just got a new 5000/200PX, we are running Ultrix 4.0, with the Xtm2d
server, but R4 clients, and the mwm window manager. Normally, response from
the window manager for actions like opening/closing icons, and moving
windows is instantaneous. But I have noticed that if I use xloadimage to
install a 1280x1024 8-bit color background screen, response time plummets.
It can take up to 10 seconds to fully open a simple xterm window (and does
not appear to be swapping either, we have 72 Meg of RAM). If I install
smaller bitmaps the response time gets better as the dimensions of the
image get smaller. Response is even worse if I start Xtm2d without the -su
option. The same thing happens even with dxwm, but it is not as severe.

I have also had the system freeze up on me entirely twice. First keyboard
input is dead on the console, but the mouse can still open/close windows,
but not pull down menus, and it can even copy/paste/enter commands into the
xterms. But after a few minutes of this, the mouse freezes up, and other
users are suddenly dead too.

Any ideas on either of these problems? Are the two related?
