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.
