Try experimenting with different screen settings. The colour depth will affect it as AWT has to convert everything to a common raster format.

Some example timings from my PC:

 Resolution | Depth | Time taken 
------------+-------+------------
 1280x1024  | 32    | 215ms
 1280x1024  | 16    | 155ms
 1600x900   | 32    | 235ms

My adapter cannot do 24bpp or 64bpp so I was unable to test with those depths, but I would guess that they would require more CPU cycles to convert.
