If anyone wants to try, you're welcome to the code - you just need to
supply a history file.

I'd agree, but I think switching INN to something where you can
parallelise article reception with getting stuff to disk is
essential... when it has to go to disk it can still keep up with the
article rate (even when running with logging & transactions on), but I
doubt you'd get the articles received and stored to disk at a
sufficient rate.
