Andrea,

Thanks and I am impatient to see your benchmark results.

If you have time, could you perform two benchmark runs to compare ThreadLocal vs ConcurrentLinkedQueue modes: In RenderingEngine class: /** use ThreadLocal or ConcurrentLinkedQueue to get the thread RendererContext / / TODO: use System property to determine which mode use */ public static final boolean useThreadLocal = true;

Just change the flag (true/false) and rebuild your OpenJDK.

Laurent

Jim, Andrea & java2d members,

I am happy to announce an updated Pisces patch that is faster again: Laurent, I cannot comment from the code point of view (haven't really read the patches), but from the performance standpoint: amazing work! I plan to give your patch another test next weekend on a full blown GeoServer to see how it behaves in a full application. Cheers Andrea -- == GeoServer training in Milan, 6th & 7th June 2013!
