I am having a problem with slow GUI's over an X11 connection.
The program i am running is matlab
It is installed on a F6 machine and a F8 machine(we've tried F9 as well)
No matter how we ssh -X to the F6 Machine we get a snappy fast gui when running matlab
(meaning I can connect to it from a F6 or F8 machine or even from OSX X11 and it runs great)
but on the F8 machine it moves like syrup, and become virtually unusable.
I am still trying to narrow down whether this is because of a different version of ssh or a different way that the windows are being drawn in Fedora 8. (Compiz is disabled and I have the latest JRE). I was hopeing someone has experienced similair problems and might be able to shed some light.
I have tried disabling all firewalls, ssh -YC, editing sshd_config to allow X11 forwarding, and many other non ssh related things, like installing latest JRE, disabling compiz, making sure graphics driver were running top notch. But the only way I can seem to get a fast interface is if matlab is running on F6.
Also it seems to be on the sshd end because when I use OSX X11 again it works snappy if being served from a Fedora 6, but slow as heck if being served from Fedora 8.
So I guess the question is , has there been any big changes to ssh since Fedora 6?
Or are the windows drawn differently now that would cause these problems?
Let me know what you guys think.
