r.surf.contour time to run?

[Neel Smith]

I'm trying to create a DEM from a rasterized topo map using r.surf.contour.
Running on a DECStation 5000, it takes several days (3-4) to work out
a 400 by 400 pixel area, even though it's getting from 50-75% of the
cpu time!

Is this possible?  I'm interested in looking at data that's a whole lot
bigger than 400 by 400 pixels!  Is there some better way to get a DEM
from a topo map?  Am I doing something wrong?

Any advice appreciated!
