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:

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of activities in this area in the past, so some of the information here (especially on the linked wiki pages) might be outdated.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 master builds.
  • A test methodology for measuring and comparing performance data of 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.
  • startup performance improvements
  • ODF load/save performance improvements
  • Performance oriented analysis of's framework

Work in progress


  • To-Dos

Probably a lot - please continue here.




  • What's going on in Writer load/save performance see here


For finished work see Calc/Done/Performance.
