Hello,

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
allowingperformances 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
