Very slow X performance on X terminals

[Anand]

Hi,

I am trying to set up some X terminals to run of a poweredge 1750
running redhat 9. The server is dual 2.4GHz w/4GB RAM and is on a
Gigabit feed. The clients are on a 100Mbit feeds. When a user resizes
any application window the redraw progresses in steps and slow as a
snail. I running gdm. I tried to use
both Solaris sparc and Solaris intel based system and do not see this
problem. I need to get the linux up and running.

Any help/pointers will be appreciated.

Thanks
Anand

What clients? Which server? Is it only the resize or is everything slow?

You should be more clear in your problem description. X11 on Linux in
general runs very well, you know.

I switched to KDE desktop instead of GNOME and the resizing and
window refresh are perfectly normal. Only for the fact that If
a second uses tries to logon to the Xserver, he gets a DCOPserver
not running message.

Didn't had time to fix/debug that, so installed FVWM on the box
and it works as expected and behaves the same way like the solaris
boxes for resizing and refreshing of windows.

I guess gnome has more overhead with lots of bells and whistles that
slows down the Xserver performance. How can one disable all the fancy
stuff in gnome desktop ?

I'll try and clear up the 'nomenclature' here.

The X server is actually the program which displays on your screen, captures
mouse and keyboard events and sends them to the X client. The client is
what we think of the application. The application starts up and usually
enters an event loop and waits for 'commands' from the Xserver.

It seems a little confusing, but consider that the X server is what controls
the application program.

Good luck.

understood, I should have used the terminlogy Xserver and Xterminal boxes.
So, how can I get rid of the bells and whistes in gnome ?

Go into it's config and check out the window manager settings. And/or
change window managers (again from within the gnome config).
