Description
MapGuide exhibits lacklustre scalability on multi-cpu machines. Portions of csmap's coordinate system transformation library are not thread safe. This submission reduces the scope of the existing coordsys transformation mutex and adds a batch processing optimization for linear geometies.
During the course of profiling, the AGGRender FindFont call also consumed significant time. A straightforward optimization was implemented to retain the last font used so that it can be easily reused when rendering labels for multiple features on the same layer.
