database performance: Java Linux Databases: JDKs
Some surprises here: some unusal variations depending on the database backend.
Some produced very strange results that would need to be investigated further.
The decision of which JDK to use is more likely to be determined by the application server or operating system, as under most circumstances they all perform similarily, but you should ensure that there aren't any specific issues with your database system (ie: see Firebird)
IBM's JDK is the one that has the most varying results.
It would seem that the IBM JDK uses a different threading model which causes a lot more load on the system than the other JDKs.
This in turn can cause a drop in performance in heavily multi-threaded applications.
