[ietf-dkim] Comments on -overview document?

Eliot,
I think we should treat the issue by stating that in the mixed
environments currently being tested a 10 to 15% cpu usage has been
noted. This will allow the SA types to adequately engineer a DKIM
solution based on their layout. When you think of all the edge
processing, filters, heuristics, etc, that is almost all cpu. The only
IO problems I have is trying to find an ever increasing mound of
storage.
Thanks,

If

The counter-point, to claims that email is i/o bound, is that modern
requirements for filtering alter the equation quite a bit.

That's why I was intrigued to hear the comments about being i/o bound
come from
folk doing empirical -- real-world -- testing of DKIM.

That said, these days it is nearly always true that one can set up a
server hub
to use most of the cpu, no matter how much i/o they have.
