Hi, I want improve the rendering of vector features in QGIS all possible. This fantastic GIS desktop is very slow when it renders large datasets for far map scales.
I have opened a new branch of code in the repository of QGIS (http://hub.qgis.org/issues/8725) to fix it and drawing tests give me ~3x faster that original code. But there is other important improvement related with data reading. I have experience with "FileMapping" capability which does the read of files very fast. I don't see in OSGeo4W any library package that provide support for this capability. There any? If it does not exist and the community considers interesting to add this support, I propose "boost" http://www.boost.org/ (or part thereof) that provides this functionality. It is cross-platform and open-source. Could OSGeo4W add this package? What think? Best regards
