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: dev@performance.openoffice.org

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of activities in this area in the past, so some of the information here (especially on the linked wiki pages) might be outdated.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.

To-Dos

Probably a lot - please continue here.

Work in progress

Startup

• Performance/Startup#Issues
• Performance - Analysis (Windows)
  • File I/O done by OpenOffice.org during startup
  • Measure cold startup time for OpenOffice.org 3.1 and svdem.exe (minimal VCL application)
  • [1] Reorder symbols within a library to reduce I/O

Writer

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

Calc

• Calc/Performance/The Ou case

UEI and Case Documents

Helpful Tooling and Resources

Test Environment

Popular reference configuration(use similar env on Hamburg and Beijing)

• valgrind - debug / trace memory usage
• callgrind - call graph profiler
• speedprof - a quick / hackish sampling full-stack-trace profiler & visualisation tool
• APPR - a performance regression tool suite
• Performance Related Test Documents
• VTune - profiler for Windows and Linux, commercial product
• TrueTime - profiler for Windows, commercial product
• AMD CodeAnalyst - profiler for windows, optimized for AMD, VisualStudio integration
• Performance/Tools/VerySleepy (HowTo) Very Sleepy 0.4 - open source profiler for windows, works on any cpu, very easy to use
