Perfomance issue - back buffer
I`m having trouble with the back buffer issue that has been fixed in Java 1.6. I`m still using Java 1.5. Because it`s a large system it`s not easy to upgrade over night.
Part of the system is a lightweight machine with a 400Mhz VIA Eden and 256 MB memory. During startup the machine has a lot of trouble with the back buffer issue, and it lasts for about 10 min and then the machine runs smoothly for the rest of the period. The GUI is still responsive during startup if you know were to push, but it`s not usable because of the gray rectangles. Is there any way that I can optimize the JVM faster, so it starts running more smoothly sooner? I`m already using -Xincgc. This is a real-time system, so performance is really important
If there is anyone that know any tips or tricks regarding this issue I would be happy to hear them

I think you'll have more success upgrading that weak machine to something with a little more power. This is not a question of upgrading the machine, you need to replace it. If you configure the new machine properly it shouldn't take a long time to make the switch.
That`s not possible because this machine is the only one I available. It`s decided by the company that this is the machine we are using for all our systems as remote control. It takes over a half year to classify a new machine so we can use.
But it`s not a problem that the machine is to weak, it`s been running for over an hour now and the GUI is very responsive. The problem is the first 10 minutes after startup, before the JVM optimizes.
By the way the machine is running java 1.5.11 on Linux. This is suppose to be a "quick fix" before we have the resources to upgrade to Java 1.6 and the back buffer issue is fixed
