Hi Jerry,
I hope this is not under NDA:
You may want to try your application with the latest developer release of
J2SE 5 for Mac OS X. You can set a system property which allows choosing
between the Quartz rendering engine and a software rendering engine implemented
by Sun.
The performance characteristics are quite different between the two engines.
In case the above shouldn't work out for you, I have started experimenting
with doing all the painting in a software rendering engine implement by myself.
The performance is surprisingly good when compared with the Java2D renderer
which comes with the JVM.
It beats the Java2D line drawing code on the Mac and is only slightly slower
than the area filling code.
On the PC, depending on the graphics card in use, it is slower than the Java2D
code or at par for non-antialiased and opaque rendering. For translucent
and antialiased rendering it performs very good.
It shouldn't be too hard, to change your application, so that it alternatively
creates a BufferedImage which uses Java2D, or one which uses the software
renderer.
