The performance project
This wiki page is the collaboration entry point for the OOo Performance project.
For questions and discussions, please use the new mailing list from the performance project: email@example.com
When you plan to file an issue with regard to performance, please make sure to add the keyword performance
The official (incubator) project was started February 2009, but there have already been a lot of activities in this area in the past, so some of the information here (especially on the linked wiki pages) might be outdated.
This page will be cleaned up soon.
- A test system for collecting reproducible and comparable performance data of OpenOffice.org master builds.
- A test methodology for measuring and comparing performance data of OpenOffice.org master and CWS builds.
- Lightweight tools that automatically collect performance data and assist developers in identifying performance bottlenecks.
- Real life test scenarios which will also be reflected in the automatic performance tests.
- OpenOffice.org startup performance improvements
- OpenOffice.org ODF load/save performance improvements
- Performance oriented analysis of OpenOffice.org's framework
Work in progress
Probably a lot - please continue here.
