1 process. 1 cpu machine. 1 gige card. As much ram as you want. No
syscalls. Must exhibit a load curve similar to:

y
| ...............
| .
|.
+----------------x

Where x == requests per second sent to the machine and y is the number
of resposes per second sent out of the machine. Hint: read the phttpd
and /dev/poll papers for an idea of the breakdown that happens for larger
values of x (make the cpu slower to cause the interesting points to move
lower). For a third dimension to the graph, make the number of total
connections the z axis.

Ok, TUX can do it. Now list for me some server that really matters
other than web and ftp? If you say databases, then I agree with you
but I will also reiterate how the people who need that level of
database performance is "nook and cranny".

I think there is nothing wrong with doing a TUX module for situations
where 1) the server is important for enough people and 2) scaling to
the levels you are talking about is a real issue for that service.
