I agree. For me it is a serious issue. When it comes to working with rasters I have given up using QGIS.<br><br><div class="gmail_quote">On Tue, Feb 28, 2012 at 10:44 AM, Paolo Cavallini <span dir="ltr"><<a href="mailto:cavallini@faunalia.it">cavallini@faunalia.it</a>></span> wrote:<br>

Loading a raster is in certain conditions unacceptably slow, and as we have seen this<br>
is largely due to stats collections. At least for GRASS rasters, gdal knows he cannot<br>
compute stats; e.g. in R:<br>

Geospatial Data Abstraction Library extensions to R successfully loaded<br>

Warning message:<br>

<br>
Is it possible that QGIS is trying to calculate stats, and this is a reason for the<br>
slowdown?<br>
All the best.<br>
