Good stuff. Is there anything I can do to help? I do have an up to date
version of JDK 8 sources on my disk, maybe I could
try to apply the patch and take it for a spin in a real GeoServer and see
how it goes.

By the way, wondering, is there any other benchmark to try out?
A possibly interesting one is this, where the author re-coded some selected
methods of Graphics2D for maximum performance
(but sometimes lower antialiasing quality) and created a applet to compare
the results in a number of synthetic test cases:
