Currently we use jtds for connecting to our SQL Server databases. I've always taken it for granted that we use it due to performance and reliability reasons, however, it's usage pre-dates my employment.
All of that being said, we are now playing with the idea of moving to SQL Server 2008, which jtds has limited support for. Initial tests seem to indicate that jtds has better performance than the Microsoft supplied driver on 2005.
So my question is does anyone have any empirical evidence or any other good information otherwise indicating which jdbc driver is best suited for use with SQL Server 2005 and\or 2008?
Is jtds better? The driver supplied by Microsoft? Something else?
I've thought about profiling, but have doubts about whether this will really prove anything.
