running v.surf.rst on grass 70svn on an AMD vishera 8 core 3.5 Ghz cpu
with 8 GB RAM . Fired it up with the defaults for a section of Western
North Carolina with 77 million bare earth points to create a 23 million
cell 20 ft resolution grid. I will attempt to attach screenshots of
completed grid and grid complete with v.surf.bspline. Region was set to
output v.surf.bspline raster.

Complete command sequence below:
