Im working on an N-Tier distributed web application thats made with COM+ (written in VC++). I've developed data access components for SQL Server, Access, Oracle, MySQL, and DB2 im trying to find the highest performance database that will be used default with the app. Theres gonna about 100,000 user records stored in the database, along with tons of other info. Another server will house a database that will store user state information (persistance state), and the app will frequently read/write to the database.
Any suggestions on which database i should go with, based on performance?
