I am a "little" overbusy for now ; I have to set up GitHub but didn't had the time to do. I also still have tests to do, the patch works fine for our software and the unit testing is OK but I have to test it with other programs (DbVisualizer).
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 ?
