You can speed things up quite a bit by using over-relaxation as discussed
at e.g.

The basic idea is to figure out what size of change the relaxation method
would have taken, and take a step larger than that by some factor gamma.

More generally, that site
describes a fancy fortran program for doing calculations of this sort. You
might want to look at it.
