Additionally running OOo as part of the build to generate the data is tricky, so I haven't done such a build yet. Though with my headless plugin (http://blogs.linux.ie/caolan/2007/05/04/headless-ooo) I'll give it a whirl at some point.

There was a project (GNU Rope) to do something similar, but it's apparently been abandoned. 0.12 sec is what percent of the original startup time? How does this ordering compare to that produced by -freorder-functions when fed -fprofile-arcs output generated from app startup? Interesting project.
