Maybe it's the qsort(), maybe it's the i,j loop within a loop. # spearfish example of the slowness g.region -d v.random n=50000 out=rand50k v.db.addtable rand50k column="elev INT" v.what.rast rand50k rast=elevation.dem column=elev Could someone in the know add some profiling how-to tips on the Wiki development page? http://grass.gdf-hannover.de/wiki/GRASS_Debugging#Using_a_profiling_tool see also this thread WRT v.rast.stats slowness, http://thread.gmane.org/gmane.comp.gis.grass.devel/22730 Hamish _______________________________________________ grass-dev mailing list [email protected] http://grass.itc.it/mailman/listinfo/grass-dev
