Project will achieve the goal: maintain good performance and evaluate OOo.

==== system issues ====
+
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of activities in this area in the past, so some of the information here (especially on the linked wiki pages) might be outdated.
−
* Linux / Linking - relocation processing is very slow ( [http://ooocon-ljudmila.kiberpipa.org/media/Bloated_Michael_Meeks/video.ogg ogg video],  [http://go-oo.org/~michael/performance.odp odp slides] ) several possible ways to fix that
+
−
** re-ordering symbol & elf hash tables to improve cache locality, lots of good & simple ideas here.
+
−
** -Bdirect implementation [http://sourceware.org/ml/binutils/2005-10/msg00436.html] - gaining little traction.
+
−
** exporting Vague linkage more cleverly & using RTLD_LOCAL where possible
+
−
** basic linker optimizations:
+
−
*** don't export *UND* in .hash table
+
−
*** sort syms & dynsym entries more intelligently
+
−
*** .hashvals optimisation
+
−
* Linux / I/O scheduling & pre-loading is poor
+
  
−
==== General I/O & memory issues ====
+
This page will be cleaned up soon.
−
* Image strip layout - our images strips are huge & unwieldy, layed out [http://blogs.msdn.com/oldnewthing/archive/2005/08/05/448073.aspx horizontally] and are 'cached' in scattered files - this is fixed in CWS ka009, which never seems to get integrated.
+
−
* Configuration information scattered across many files
+
−
* UI configuration - tons of scattered files
+
−
* .rdb files - loads of empty space, mmap + random access pattern
+

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of activities in this area in the past, so some of the information here (especially on the linked wiki pages) might be outdated.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

Deliverables

  • 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
