Hi Hamish... yes.. my threshold is really small (30 cells, because I need a very detailed stream network in output), and this can probably have a strong effect on the time of analysis... However I'm really surprised of your results with 170000000 of cells... and 2 Gb of ram...!! really impressive... I have tried over two different computers (with 2 Gb of ram), but the result is the same... so I think that the problem is not on the quality of the ram or other similar thinks but on the dimension of the dataset...
I will try with different resolution as soon as possible... but at the end I need this resolution because I have "cleaned" the dem with v.breach to obtain a hydrologically correct dem and now I must use this dem to derive the drainage... Many thanks for your interest....
