Another consideration is how much time you spend using each connection
vs. how much time it takes to establish each connection.  A thousand
simple queries over the same encrypted connection might be significantly
faster than running each query over a separate unencrypted connection,
which in turn will probably be significantly faster than using
separate encrypted connections that must each carry out a relatively
expensive key establishment.
