Hello

I'm running applications on Solaris 8 machine accessed using XWindows.
There is slow network connection to the machine.
Native applications are running slowly, but the performance is aceptable.
Java GUI applications are extremely slow.

How can I make it appear faster ?

I cannot change the connection speed, but I'm developer of the java applications, so I can modify the source code, if necessary ...

Best regards
Miro

What kind of java applications are running slowly?

I suspect the best candidate for performance optimization would be to reduce the number of repaints, and to make the regions of repaint as small as possible.

If you're using JDK 1.3, upgrade to 1.4. The remote-X performance difference is huge.

Also consider using VNC instead of X if that's at all possible -- it's much better over a slow link, TightVNC especially.
