I had two seemingly identical TeX Live setups on two similar machines,
yet the faster of these ran TeX programs about 20 times slower than the
slower machine.  I /believe/ that the TeX-specific search paths on the
slower machine were somehow sub-optimal, but never really managed to get
to the bottom of it.  In the end, I jettisoned the TeX Live setup from
the faster-in-theory machine, cloned the slower-in-theory machine's TeX
Live setup to it, and thereafter all performed as it should.
