v5 v6 14 14 *** Only changed the MAP projection block to be "init=epsg:4326" instead of the projection string. 15 15 }}} 16 17 == Plan of Action == 18 19 * For the EPSG code performance problem, FrankW is planning to implement some caching directly in PROJ.4. More details to come, but on the PROJ.4 side, not a lot directly in MapServer. 20 * With really large shapefiles, some profiling revealed that a lot of time is passed in msGetBit called by either msShapeFileLayerNextShape and msFilterTreeSearch. We acknowledge that the bit mask is not the optimal solution for very large shapefile (>3M features). the only thing we plan to do right now is to pass from a 8bit mask to a 32 bit mask. 16 21 17 22 == Test machine ==
