Just a reminder that I've stepped up to put mapnik through the paces in the FOSS4G benchmark, or "WMS Shootout".
http://wiki.osgeo.org/wiki/Benchmarking_2010 This is a friendly competition, and in past years has resulted in many new fixes and code innovations for the MapServer and GeoServer teams that have competed. They also seemed to create a good vibe of collaboration, which I admired. I figured it would benefit the Mapnik project to go through the same process and learn from the comparison. My work on projection code optimization came from my first week testing (https://lists.berlios.de/pipermail/mapnik-devel/2010-July/001199.html). Basically I knew that the WMS load tests that will be placed on mapnik will be numerous and I wanted to see whether requests/sec increased significantly if the server was run with more potential threads. I found that it didn't, until I removed and fixed up some of the thread safety code around proj4. Anyway, if you are interested in helping test, supporting on any other level, or have questions, just get in touch. In the coming weeks the actual benchmarking server will finish being set fully up with the same data and styles to be run against each software teams builds. The WMS spec was chosen as a reasonable way to load a server with random bounding box requests to test raw rendering speed under different styling scenarios. I plan to test both the newly released WMS implementation from Geofabrik (mod_mapnik_wms)[1] and a yet-un-released boost::asio-based server I have been working on (aka. paleoserver). For those that are interested all the styles and scripts I create along the way will be available in the osgeo svn [3].
