Performance

I'm getting twice the frame rate with the earlier Java 6 u 3, than with the new ones. Very weird. Can anyone give some explanation?

On Core 2 Duo 1.83ghz, integrated video (only one core is used) - 1500 (older java) vs 700 fps On Athlon 64 3500+, discrete video - 120 (older java) vs 55 fps

The app is a simple game with a moving rectangle. I'm using Graphics2D to draw from a loop.

I have a site-to-site VPN set up with two SonicWall's (a TZ170 and a Pro1260). It was suggested to me that turning off encryption (so the VPN is tunneling only) would improve performance.
