I just replied to this on pgsql-odbc mailing list. Since we're talking
about client performance, please keep the discussion there.

Hello all!
I do some test with ODBC driver for PosgreSql, TimesTen MySQL. I compare
performance on very simple request. Database always located on same PC as
test application. Test PC - Lenovo T500, Cnetos 6.5 64, 8 Gb RAM, SSD.
I found what PostgreSql ODBC driver is slowest in comparison.
IMHO problems related to protocol used. I can't use SHM connection to
server or even UNIX socket.
