[gl4java-usergroup] Suddenly running really slow above a certain poly count

[SHL <shl...@ya...>]

My application (using Java with gl4java) tends to run
smoothly up to a point, but when I increase my polygon
count by even a little bit above a certain threshold
it all of a sudden becomes *unresponsive to input* and
runs *really slow*. 

The weird thing is if I compile the most poly
intensive object into a display list and call the
display list everything is really smooth again.
Supposedly display lists are supposed to be faster,
but I do not think the display list *alone* caused
that much of a sudden performance increase. 

The strange thing is that if I up the polygon by even
a little bit above a certain threshold it *suddenly*
becomes unresponsive and slow. 

I guess I could just use the display list, but I fear
that there is some underlying problem that I have
missed. 

What could be causing this and how do I fix it? Maybe
it is a java/gl4java specific issue?
