Hi, I have filed a new ticket for this: http://trac.osgeo.org/gdal/ticket/3165
A summary of my tests with gdalinfo -mm Processing 9 .sid files via a .vrt takes 2h:47m Processing 9 .sid files directly takes 0h:57m Processing 24 .tif files via a .vrt takes 0h:27m Processing 24 .tif files directly takes 0h:9m Working via a .vrt is approximately three times slower than working with the tiles directly and working with .sid files is much slower than .tif files.
