Hi Philipp, 

I can confirm that (some) Java apps are really slow via LTSP (and I 
think they became slower with every upgrade).

Could you check if the bottle neck is CPU, memory, or bandwidth?

Especially apps that use multiple threading in Java seem to launch too 
many processes.

Furthermore, Java uses its own widgets and hence all window elements are 
transmitted as bitmap graphics (as opposed to other X widgets) - AFAIK.

I wonder if there are tweaking parameters for the Java VM - or faster 
alternative VMs to be used?

Ralf
