Throw in frequent SYN/FIN/RST's because of small Web connections, SYN
retransmissions because busy Web servers have full listen queues (or are
being SYN-flooded :-), TCP's that ack every packet (Linux 1.0, I believe,
and maybe later ones), TCP's that wind up acking every packet because their
delay timer is less than an MSS prop time across a slow link (Solaris, for
links < 10KB/sec), and dup acks due to sequence holes, and you might
handwave the 7%.
Add in old BSD keepalives, silly window syndrome window management, window
opens for systems with too small windows...
