Are you using an Extended kernel, because this is not necessary in your
case, and something like Exact_predicates_exact_constructions_kernel would
be much faster.

Also are you including the time required to construct the input Nefs? If
you're building them with something like OFF_to_nef_3 expect it to be very
slow. You're better off reading the OFF into a Polyhedron_3 and converting
that to a Nef.
