Hi, I'm troubleshooting a fairly large application built on top of the NetBeans 6 platform that is causing the X-Server to chew up up a lot (30%-50%) CPU when all it seems to be doing is refreshing a blank (no data) Map (we're using Openmap) once a second. (I'm going verify that this week and ensure the entire app isn't getting repainted or revalidated once a second or more.) It is running locally and I'm running it with the -J-Dsun.java2d.pmoffscreen=true. (I've tried false as well.) The Java process is only taking 5% or so compared to the X-Server load.
In comparison, a similar application (uses OpenMap, but not built on NetBeans) we have uses only 2-5% total CPU with the map populated and updating more than once a second. I've tried all the flags documented in the Java2D whitepaper (http://java.sun.com/products/java-media/2D/perf_graphics.html), but I haven't been as fortunate this time for a quick fix. (I did use the -J option to pass the VM option through the NetBeans exec to the VM.) (BTW, this is a Sun Blade 2000 UltraSparc III+ with a GFX-450 Graphics card, running Solaris 8. It has 4 GB of memory and I significantly increased the shared memory segments from the defaults.) To get some insight into what was going on, I used the X-Server proxy, xmon, to monitor the X-Event traffic to see what was going on and noticed that there seems to be a lot of X-Event traffic. I was expecting more bitmap type operations where the Swing's buffered image would be sent to the local X-Server rather than the nearly 2000 primitive draws per minute. It is almost as if Swing isn't double buffering. I've also tried using the -J-Dsun.java2d.trace=<optionname>,<optionname> to get a log of the messages, but nothing was printed. (I've tried it on Java 5 and 6.) Does that work on the newer versions of the VM. (I need to run a test as well outside of the NetBeans app to see if the NetBeans platform is intercepting it somewhere.) Does anybody have some suggestions on what might be going on? Thanks!
