For the next release of its open source MySQL, Oracle is making a number of changes designed to vastly boost the speed of the open source relational database management system. Such a sizeable performance bump could help organizations save money in server purchases, because it would require fewer servers to run large jobs. Or, it will allow them to run complex queries that might have taken too long to run on earlier versions of the database system, said Tomas Ulin, Oracle vice president of MySQL engineering.
