Okay, its official. My brain isn't working.
The different kernels were tested on two different machines. The one
running 2.4 is *just* enough slower that the packets start to pile up
and end up waiting in the socket buffer. By slowing down the packet
sending I get results that are invariant with the number of packets.
Sorry for the false alarm guys....
