Most large sites don't use keep alive.  It ties up a worker thread 
waiting for another request to come from your home PC, whose link is 
this slow megabit-plus high-latency straw compared to our OC-48 firehose 
which is 3-4 hops from MAE East.

The big wins might be in content delivery (video downloads).  In this 
case, you *have* to keep the connection open or risk a poor user 
experience.  However, you can't use this if per-user DRM must be applied 
to the stream.
