I've faced slower performances since 9.1 driver version. After some investigations, I've found metadata caching has been changed, and I have introducted a new caching method allowing performances to be similar than of 9.0 driver version.
The methode implements a caching object in the AbstractJdbc2ResultSetMetaData.
Has anybody else accountered this huge slow in performances ? Is anybody interested in testing this caching ? Christophe
