It may be used remotely, but currently we're trying to get it to run without excessively loading up the local X-Server I think we should probably add a -nonFancyMode flag to our app where it doesn't use translucent panels or gradient shading on machines with older graphics cards or when remoting the app. > In the local server case, have you tried setting > this env. variable: J2D_PIXMAPS=shared . It may help. Oddly enough, when we use "shared", the X-Server load goes up quite a bit (on the order of 30-50%), whereas when we use "server", the X-Server load goes down to more normal levels (like 5-10%). Why would that be on a local box? Seems like shared memory would be more efficient?

That's a good idea. In the past, we've put that in the scripts, which would detect whether the display variable was set to the local display or the remote display. We also had to put in logic to detect certain graphics cards since they responded differently as well.
BTW, (you all might have considered this already) it might be nice to have a command line setting like -bestSettings where the Java2D layer could attempt to automatically measure and configure itself with the most optimal settings for lowest overall load (Java Application+XServer) and graphics responsiveness at least for the client and server running on the same box. It can take some time to manually figure the optimal combination of environment variables and command line settings to create the best performing application especially when it seems that different X-Server/graphics card tends to require different settings. (For instance, on certain Linux boxes, it was more efficient to use pmoffscreen=true even when remoting the application from the Solaris box when on a fast network.) Thanks again!
