For 2.6.0-test6, it stays constant. 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....
