using qgis I notice that it is more slow to open some raster from a
catalog.vrt rather than opening the same raster directly.
The slow is so big that when the catalog has many raster qgis take many
time to open the catalog.

Because qgis use gdal to read raster and also to read a catalog.
I guess this is not an issue for qgis. But is a question of gdal.

Before to start to do some test I like to know if there is some know issue
on this.
