You can speed things up quite a bit by using over-relaxation as discussed
at e.g.
http://www.triumf.ca/relax/doc/relax3d/node11.html

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
http://www.triumf.ca/relax/doc/relax3d/relax3d.html
describes a fancy fortran program for doing calculations of this sort. You
might want to look at it.
