Try adding the -C option to that ssh command. For images compressiong the data wont help, but for other stuff it might be a win. Note that on Linux some versions of ssh compression is disabled when privilege separation is enabled. If you can, run your window manager on the display, not the remote machine. If not go for a lightweight window manager. Also avoid fancy backgrounds and other image heavy applications. -- Dr. Andrew C.
