How to speed up Postgis raster layer display in QGIS?


i've been importing some digital orthophoto geotif files into postgis 2.0.1 via raster2pgsql tool (i also made 3 levels of an overview table - pyramid). Then i tried to import the layer into qgis via the postgis load raster plugin. It works, but the speed seems so slow its unusable at the moment.


I found a post somewhere about this being a GDAL issue, but i couldnt find if a solution has been found yet. Did anyone get across this?


Thanks



Answer




Is the GDAL driver that is slow, not qgis itself. Anyway the driver is being improved.
