I have done some "real-world" programming in Prolog and SML.  The
conventional wisdom in the LP community seems to be that the primary
path to performance improvement of logic programs is by reduction of
non-determinism.  To a first approximation, when you have eliminated all
the non-determinism from a logic program what you have left is a
functional program.  The work I was involved with, trying to get
quasi-real-time performance from Prolog, bore this out.
