NB67PerfPlan

Plan for NB 6.7 Performance improvements

This is an implementation plan for performance improvements targeted for NetBeans 6.7 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 6.7 (e.g. fixing reported performance bugs is not included).

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

  • [[File:]]

  • Image:yes_NB67PerfPlan.png Jarda: P2: Improve startup module cache IZ 156330


March 9

  • Image:yes_NB67PerfPlan.png "Pavel": Speedup project open and scan - optimize test dependencies computation IZ 158881
