gdal plugin is generally better for rendering very large data than the native raster plugin, because gdal (and the mapnik gdal plugin) supports overviews. But the raster plugin has been seen to be 2-5x faster (has less overhead than gdal and no mutex locking) for smaller data. If we added overviews reading support (for geotiffs) to the raster plugin when we might have a faster option than gdal overall.
