Developer’s Corner: Achieving Extreme GeoServer Scalability with the new Marlin vector rasterizer

As you probably know, GeoServer is a Java based software, so its performance is heavily dependent on what the Java Virtual Machine and the Java standard library can offer. Over the years the GeoServer developers have been pushing the boundaries of what can be done by replacing portions of the Java standard libraries by adopting faster replacements, for example, the turbo jpeg encoder, the native PNG encoder available in ImageIO native extensions, or the recent adoption of the pure java, high performance PNGJ library. One of the Achilles' heel that so far we failed to replace is the anti-aliased rasterizer contained in the...


News from OSGIS 2010

Dear All,I just wanted to write a few lines about the OSGIS 2010 event that took place last week in Nottingham, UK.As you can see from the agenda the FOSS4G tribe was represented almost entirely; people from all over the world were attending and/or presenting.As of the first day's workshops, it is a shame I have not been able to attend many of them, but just the Ordnance Survey OpenSpace event, which has been very interesting.As far as the second day's presentations are concerned, I had the opportunity to check of them. I have to say that I have much...


Sharing thoughts about FOSS4G-IT 2010 part 1

Ciao a tutti,as announced in a previous post today we start to share the materials produced for the Foss4g-IT conference. Thanks to SUPSI, that in Lugano was host of this nice event, we had a very good time.In this first part we are sharing the slides of the presentation that Ing Simone Giannecchini, founder of GeoSolutions, illustrated at SUPSI’s Aula Magna.In this presentation you’ll find the state of art as far as Geoserver and its latest features are concerned: integrated security, dynamic symbolizers and ImageIO-Ext GDAL support. Also, quite interesting, it’s the use case describing an integrated system for scientific...
