NB68PerfPlan

Plan for NB 6.8 Performance improvements

This is an implementation plan for performance improvements targeted for NetBeans 6.8 release. It covers work done by the performance team and also many important issues solved by other teams. Still, this is not all performance work being done for 6.8 (e.g. fixing reported performance bugs is not included).

For an overview of what has been considered see the list of performance topics.
