Thanks. Originally we were using the Microsoft JDBC driver. After this problem was resolved, several developers wanted to try a different driver, I'm not exactly sure which one(s) they tried. The performance was a little better (about 10%), not much, but enough to decide to do more testing.
I'll check to see which driver they are using.
