How to enable GLX? [3]

I am using Xmanager Enterprise Edition with GLX support declared.
I am connecting through Xbrowser (XDCMP) to my debian box. Both my client (WinXP) and server PCs are capable to OpenGL.
OpenGL application, tuxracer as an example, locally runs at server host smoothly - so, glx works locally.
But there are huge lags when i try to run tuxracer trough Xbrowser, glx doesn't works.

The question is: how to set up all the things to support GLX in XManager Enterprise?

Here's info on glx from Xmanager connection:

Xmanager log is attached.

Your glxinfo shows that glx is functioning normally. In my experience, Tuxracer lags even from the console environment. Sometimes, glx applications require high system resources and can cause application slow down. But moreover, you may have insufficient bandwidth. If it is possible, you should test it within the same network environment.

If your problem continues, you should post the name and version of the remote host and the application.

glxgears application runs on remote server's console at 450 FPS
And it runs through Xmanager at 100 FPS
This is a huge slow-down :(
Both client and server hosts are OpenGL-capable, and moreover, client host is much faster (both on CPU and Video).
Client and server stands in one network environment: both connected by patch-cords to single swithing hub.

What do you mean by "name and version of the remote host"?

I have a fresh Debian Etch, here is all installed packages related to X server:
x-window-system-core 6.8.2.dfsg.1-11
x11-common 6.8.2.dfsg.1-11
xlibmesa-dri 6.8.2.dfsg.1-11
xlibmesa-gl 6.8.2.dfsg.1-11
xlibs 6.8.2.dfsg.1-11
xserver-common 6.8.2.dfsg.1-11
xserver-xorg 6.8.2.dfsg.1-11

As I tested in my machines (Windows XP with SP2 and Red Hat 9.0) and I get around 340 FPS in console and 180 FPS with Xmanager which is I think it¿s pretty close considering it is happening over a network. My machines are connected through10Mb hub.

If you are running heavy programs on your PC, you may get low FPS rate.

Try setting the Backing Store option to when mapped. You can find this option at Xconfig > Default Profile > Advanced tab > Backing Store.

Also, check your switching hub, and see if it is doing anything than may reduce the performance.
