hi are you using the following command line option -Xincgc
there is a bug in java 1.4 when using the -Xincgc command line option it causes the garbage collector to run too much and causes a very significant slow down in 1.3.1 -Xincgc helped a lot in eliminating GC pauses in 1.4 its broken in 1.4.1 it is fixed there has always been some slow down in using -Xincgc (even with 1.4.1) its the price you pay for smoother running 1.4 default GC (ie without -Xincgc) seems much better than 1.3.1 (without -Xincgc) there is a bug report on this (i'm off line - so cant find the bug id but its listed in the bugs fixed in 1.4.1) the impact of this bug is very apparent regards john > Joachim Diepstraten wrote: > > Hi > > > > Hmm that's strange actually JRE1.4 should give you a boost also. > > JRE1.3 and J3D1.3 doesn't work 100% together could be the WGL-error you > > get, because FullScreen-Support only works with JRE1.4. > > Still must be some sort of obscure bug in the 1.4 machine. > > > > Or are you using 1.4.1? > > > > About the profiler hmm I'm not sure I've never used one before (sorry) > > > We've been using Borlands OptimizeIt suite for profiling Xj3D.
