I'm not really sure how this occurs, but it does not seem quite right. If one does a write of 125 bytes, it seems to get fragmented into a 100, and 25 byte packet, and sent seperately. At first I thought this might be some weird artifact of TCP_NODELAY, but this does not seem to make a difference. Regardless of the way the data fits in mbufs/clusters, I think that it someone does a write syscall, and it fits within the mtu/mss/window, it should be sent as one piece. Is there any reason why it is not done this way? --Chris Csanady
