hi

there are some performance issues with jogl on my powerbook 1.25 with os x 10.3. the gears demo for example does not run smooth. in xith3d rotations of simple objects do not run smooth. it stucks about 3 times a second.

my java version:
java version “1.4.1_01”
Java™ 2 Runtime Environment, Standard Edition (build 1.4.1_01-99)
Java HotSpot™ Client VM (build 1.4.1_01-27, mixed mode)

the 1.4.2 dp1 does not work.

i use the jogl build of 5 th september

any hints?

thanks

I’ve also encountered this repeatedly and for a long long time and haven’t been able to figure out what’s causing it as the garbage collector is kicking in and causing the pauses, even if there is apparently nothing to collect. If you profile it, you will find that the slowdowns are coming from fullGC() calls by the JVM.

I’m using the November build of JOGL from here http://homepage.mac.com/gziemski/projects/ with the 1.4.2 DP 1 and I haven’t noticed this. The gears demo ran smooth the last time I checked.

now i am useing the november build too. it did not work with java 1.4.1. but with 1.4.2 its fine and runs my project much smoother. but there are still some steady stucks.

when i check the running java thread in process-monitor it throws a lot of errors (more than 15000).

thanks for your hints.
