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

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.
