I did try out Gunnar's new JDBC driver on two very simple query-only
applications.  It was about 15% slower on one of the apps and 10% faster
on the other, compared with jdbc7.0-1.2.jar.  It worked correctly on
both tests.

Neither is particularly representative, but the fact that one's faster
an one's slower is surprising.  I have not had the time to dig into why
the discrepancy.
