Hello Ravyn, Im fairly new to geoserver and openlayers, anyway: Pink tiles are primarly a indication your script cant access the remote (WMS) resource and load its stuff. It can be some error on your code (client side); permission issues on geoserver side or (I guess), missconfigured layers. I personally had a bad experience with some layers that geoserver didnt recognized the source datum, what leaded to tomcat's crash e.g.
Ca you use layer groups? It avoids lots of overhead when rendering for the final result. There are some considerations on installation instructions http://docs.geoserver.org/stable/en/user/production/java.html#production-java from there "JREs other than those released by Oracle may work correctly, but are generally not tested or supported. Users report GeoServer to be working with OpenJDK, but expect reductions in 2D rendering performance." I tested with both (just a quick test), and didnt noticed difference, but im running on a limited RAM VPS and maybe im getting other limitations obscuring such a test. Network latency can be a issue and slow down things (well, this one is quite obvious) The way you make your code for openlayers has big impact on speed, usually, code under developement is not same code for production. I got some nice tips about this subject in here http://ol-performance.appspot.com/ Theres a option in geoserver (at least on geoserver 2.4), under JAI setting about "enable fast renderer" or something, dont know the exact text but its there.. Well I didnt tested it yet. I hope it helps Regards, -- Rodrigo Nascimento Hernandez MinasAmbiente Eng.
