I have 1.6.0_30 JRE on my 11.10 install. I have 3 GB of RAM and an Intel Core2 Duo CPU T6600 @ 2.20GHz × 2.

Whenever I use my Java to play a game, the Java runs at about 4-5 FPS. When I used Windows, I found that I could get around 40 FPS. I'm not too terribly worried about this, but are there settings that I can tweak that I don't know about? If not, why is it that JRE Java can't do as much on Ubuntu as it can on Windows?

Also, this may be related but I'm not too sure--My fan runs very fast when running a Java application. Is there a correlation?
