Hi Paolo, Tim unfortunately in the last months I had a very little time to follow the developments, so maybe I will say obvious things.
I just compiled QGIS master under Ubuntu against GDAL 1.8 and when loading a raster I see the same message Warning: Object::connect: No such signal QgsGdalProvider::statusChanged( QString ) in /home/gio/qgis-Quantum-GIS-6a1073f/src/core/raster/qgsrasterlayer.cpp:2446 the practical difference I see is that, as Tim describes, that rasters are slower to open the first time, but then are faster as before, if not more. This seems to me not a big deal when opening quite small images, but it can be when opening multiple images at one time or when adding very big rasters. For instance I have 3GB landsat images with overviews that before these changes opened in a nick of time, now -the first time- they take a few seconds (10/15). The same images without overviews before the changes took 10/15 seconds to open, now -the first time- it takes much more. Another issue I guess can be if the rasters are stored in a place where the aux.xml cannot be written. I guess that the right behaviour is the new one, but maybe it is worth add an option to avoid collecting stats on raster load? cheers -- Giovanni -- On Tue, 2011-08-09 at 15:49 +0200, Paolo Cavallini wrote: > Hi all. > With current master, I get bad performances in loading rasters (a <12Mb takes > >5 > sec); when double-clicking it from the QGIS browser, it is far slower (>20 > sec).
