Re: [JAVA3D] Efficiency (follow up)

how much memory do you have? setting max to 1024 on a 128 meg system will cause disk swapping which is orders slower in terms of performance (40MBs-1 instead of upto well 1000MBs-1 in ram).   N ----- Original Message ----- From: Bura Tino To: [EMAIL PROTECTED] Sent: Sunday, December 01, 2002 5:50 PM Subject: Re: [JAVA3D] Efficiency (follow up) Thanks for the response!!! I read it very carefully. I don't think it's a memory issue for several reasons. 1. I use -Xmx1024mb and so there's plenty of memory. 2. If I take out the setCoordinte code, there are no delays. 3. If I detach the group, update it and then reattach, there are no delays, either! (but lot's of blinking!!!) (BTW, I'll address this in another email soon... but if I keep the update code, my program does run out of memory eventually (although there are no new classes being created!!!!)) What else can it be? As a reminder, I have this code:    for (int i = 0; i < height;i++)       for (int j = 0; j < width; j++)            myTA.setCoordinate(i*width+ j, mySurface.pGet(i, j));   Many thanks!!!!  trz <[EMAIL PROTECTED]> wrote: Bura Tino wrote: > My I follow up my own message.

Try to run the prog with -verbose:gc to verify it. If it's so, you have to look where you create new objects (maybe every frame) and find a way to avoid this (reusing object or the like). And you can try to give jvm more memory with -Xms32m -Xmx64m.
