Why AWT/Swing is SOOO slow on my Linux?

Hello,

Why all Java/Swing programs seems to be very slow in GUI response on my linux. A painting of simple pull-down menu in Netbeans takes 0.5 sec. A non-responsive GUI is very annoying, it looks like when you work through a remote connection.

I tried to use different AWT toolkits (MToolkit or XToolkit), tried to use opengl pipe, but the rendering stays slow. In comparence on Windows all java awt/swing applications looks very fast and responsive. Is it a general problem of java on linux or only of my configuration?

Ubuntu Linux 7.04, JRE 6.0, AMD Athlon 64, ATI Radeon 9600 with opensource drivers (openGL works well).

Anton
