OpenOffice.org performance improvements
This page enumerates performance improvements (such as faster performance, lower memory usage, and reduced disk usage) that affect the end user (and not just developers). Also, omit issues that only affect non-final builds.

How to research
- Query the Issue Tracker
- Put performance in the keyword field (but the keyword is not applied consistently)
- Or put these keywords in the summary field (using option any): leak memory slow fast perform optim cache smaller repeat repetit unused unnecessar unneeded shrink accelerate speed duplicate
- Release notes
