Hi Paolo Does it do that every time you load that layer or only the first time? Does the filesystem permissions allow writing of gdal .aux.xml files?
My raster stats branch merge changed some behaviours and it is probably a side effect of that. One of the changes is that gdal gets full stats when trying to determine the min max of a band. It will fetch those stats quickly from aux.xml if present of if not its going to do a full stats gather just for the basic min max stats which is where you probably experience the slowness. I will see if I can find a better way to do the basic min/max stats gathering.
