My work has X Windows applications written in C and Java applications (on the same machines) that are installed throughout the US. When we want to see how everything is working for a customer, we often export their display to our Linux boxes. While exporting the display it is noticeably slower than running locally for the C applications, it is still tolerable. The Java applications are so slow that I rarely make the attempt.

The Java windows that are the worst are those that have a lot of custom graphics. The others are still slow, but not as bad. Is there something I can change to repaint the screen less often and thereby send less data across the network for the display? I would expect that to speed up the
responsiveness. If there is anything else I can do, please let me know.

Thanks,

Chip

JDK 1.4 is worlds better than 1.3 in this respect, so if you are running anything older than 1.4, upgrade.

But instead of using remote X, if you can use VNC -- especially one optimized for WAN use, like TightVNC -- you'll find that it's infintely better. You can comfortably use virtually any application across the Internet using TightVNC. The downside, of course, is that you may need to install the VNC server software on the customer machine.
