Even opening menus on graphical application is painfully slow. On the same system if I do a direct ssh connection with ssh -YC from the head node the same applications are quick and responsive. Any suggestions for what might be causing this, and how I can get the native x11 to have the same responsiveness as a direct ssh connection?
