Dear all,

Here is my first pisces (beta) patch (webrev): http://jmmc.fr/~bourgesl/share/java2d-pisces/webrev-1/ I succeed in fixing memory usage by having only 1 pisces instance (Renderer, stroker, iterator ...) per RendererContext (GC friendly). Impressive results between small and large drawings:

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: http://www.randelshofer.ch/oop/graphics/
