Performance/Tools/TrueTime
From Apache OpenOffice Wiki
TrueTime is a tool for profiling the performance of a Windows application.
I have used it a lot in the past, but nowadays I switched to other tools, so I don't know how well TrueTime works with current versions of OpenOffice.org.
For this reason, I don't move the information to the wiki (for now), but simply link to my old HTML version of the TrueTime HowTo.
