Swing JDialog slow when running remotely

Question

I have experienced performance problems for JDialogs while running my GUI remotely over X11. Does anyone know a workaround?

The GUI is fast when I run it on my local machine, but sometimes we need to run it on a remote server - which causes a significant lag until the dialog is displayed. It takes about 2 seconds to create and display them.

The problem only seems to apply for modal JDialogs (including JOptionPanes).

I had that problem with a look and feel that applied a textured image to the background of my windows. It ran fine on the gui designer's box, but when we tried it on a LTSP X-terminal, it was dog slow. We changed to an untextured look and feel, and things got much better.
