I tried this and it has helped considerably: 1. Gnome mandatory policy for NO SOUND (pulse audio is well integrated into Feisty. For example I CANNOT uninstall the pulseaudio gstreamer plugin when using feisty).
2. Gnome Mandatory policy for Reduced resources on metacity. This helped a LOT. Resizeing and moving windows would totally kill the X server. 3. Color depth = 16 4. Change the ssh cipher to a light weight one. in /opt/ltsp/i386/usr/sbin/ldm (i think - search for ldm). You can add a VERY lightweight cipher like arcfour: '-c', 'arcfour,blowfish-cbc,aes128-cbc,3des-cbc'] arcfour is basically nothingness. Openssl test show its roughly 5 times faster than blowfish on my system. Let me know if that helps.
