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.
