Dmitri,
The benchmark should catch only the "cache hit" phase. Following your advice, i
moved one of the image caches to use VolatileImages that get validated before
every use. While it takes the same time to run on unaccelerated pipeline, it
takes about 5% more to run on an NVidia card. Here is the output of
J2D_TRACE_LEVEL=4:

This is what i did to validate the VolatileImage after fetching it from a cache:
existing.validate(GraphicsEnvironment.getLocalGraphicsEnvironment()
.getDefaultScreenDevice().getDefaultConfiguration());
and the code for creating a new volatile image:
GraphicsEnvironment e = GraphicsEnvironment
.getLocalGraphicsEnvironment();
GraphicsDevice d = e.getDefaultScreenDevice();
GraphicsConfiguration c = d.getDefaultConfiguration();
VolatileImage compatibleImage = c.createCompatibleVolatileImage(width,
height, Transparency.TRANSLUCENT);
return compatibleImage;
Thanks
