I think there's not much place for optimizations left, at least not by
large factors (you need something like 100-fold speedup to make long
lines bearable).
So 2) is the way to go, IMO. As usual, the devil is in the details:
the design of a cache (or caches) that will hold the necessary data,
and don't hold too much of it.

No, I don't think you have.
Thanks.
