[mapserver-dev] Performance Testing numbers

[Julien-Samuel Lacroix]

I added the Code Sprint change results to
http://trac.osgeo.org/mapserver/wiki/PerformanceTesting


In short, we made 2 fixes:
  - Use 32 bitmask to improve reading of large shapefile
  - Fix PROJ.4 epsg file reading overhead

In short results:
  * It seems that the PROJ.4 fix removed most of the overhead of using 
epsg projection definition.
  * ticket 2930 help a lot when reading big shapefiles. In our case, 
drawing small part of more than 3M features, we got around 20% more speed.
