I am supposed to work with

Answer 1

I had the same problem with a client of my company, the problem was that the driver sqljdbc4.jar, tries a convertion of character between the database and the driver. Each time that it did a request to the database, now you can imagine 650 connections concurrently, this did my sistem very very slow, for avoid this situation i add at the String of connection the following parameter:

 SendStringParametersAsUnicode=false, then te connection must be something like url="jdbc:sqlserver://IP:PORT;DatabaseName=DBNAME;SendStringParametersAsUnicode=false"

After that, the system is very very fast, as the users are very happy with the change, i hope my input be of same.
