Yes, I suppose I exaggerated when I said "can't get any faster", but
given that the OP was talking on the order of hours for the EXPLAIN
ANALYSE to return, I assumed that the problem is one of impatience and
not clock cycles.  After all, the gettimeofday() additional overhead
is still not going to come in on the order of minutes without a
_bursting_ huge query plan.
