Good and fair question which highlights part of the dilemma.

On the other hand, how do you explain Facebook when two clients arriving
at the same precise microsecond and each sent 1 message and each waited
5 secs to QUIT. Why didn't it use one session for these two messages?
I can only presume it could be a configuration issue or two different
clients looked at two different queues in their outbound farm. Who knows?
Or Murray, there is another reasonable explanation for this FaceBook
behavior:
They found it is better not use CS (all or partly) but
forgot to remove the QUIT delay in cases it does.
In other words, they can send two concurrent messages in 5 secs less
total time, then it would take to send two messages under 1 session
which would have at least two 5 secs waits.
