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.
