Thanks all for the inputs. In the end I implemented a scripting procedure outside grass using pktools (pkfilter). I first tiled the image with some overlap area, than run pkfilter -f stdev , than crop the overlap area and then merge back the full image.
It would be interesting to find out whether this is significantly faster than doing exactly the same within GRASS, and if yes, why. Have you tried ?
