[exim] Exim Performance Numbers - 5000 email a second?

I was reading the stats of email to spam traps over at abuseat.org.

They talk about getting an average of 5000 emails a second over a day,
being 432 million messages a day. Those numbers come from comments on
their stats page.

Their live stats show numbers for the last week being more in the average
of 1175 messages a second.

Anyway, this post is more about what type of volume can exim push? I can't
imagine my exim server handling that volume of mail, I think I'm more in
the 10 - 20 messages a second maybe.

What type of setup would be needed to handle 5000 messages a second
average?!?!

What type of volume do you do?
