Hi all, it's been a few months since my last mail. If you remember, I've tried participating to Laurent webrev discussions by providing a real world benchmark using GeoServer running the public OSGeo WMS shootout. If you want to read the last discussion on the topic, this was the thread: http://comments.gmane.org/gmane.comp.java.openjdk.2d.devel/3467
Well, I'm back since I've managed to build a pure java PNG encoder that's significantly faster than both the JDK one, and the ImageIO native one (aka CLibPNGImageWriter), especially when run on OpenJDK, so I'm back trying to make the renderer itself faster for server side, headless workflows :-) (if you want more info on the PNG encoder work I'm at your disposal too, let's start a separate thread). Now, Laurent's work pretty much stopped at the fourth webrev, and I'm interested in trying to take over, provided there is a chance for the changes to be merged (either in JDK 8 or JDK 9). >From my existing experience with open source projects I believe the patches can have a better chance of being merged by avoiding code style changes, and minimizing the changes to the bare minimum that provides the most significant speedup, and then make a choice on how the arrays should be cached (the CQL approach seems to be more promising) to further simplify the code. So, if I sign the OCA, can I look over Laurent's code and build a new webrev oriented to providing the minimum of changes to the existing code, possibly trying to avoid any change that would affect the ductus pipeline? Would this be a good approach to get the improvements merged? In general, what do you suggest would be the best course of action? Cheers Andrea -- == Our support, Your Success!
