Is OpenOffice.org getting faster?

Some complain OpenOffice.org is slow and bloated. With each release there may be dozens of performance improvements, but there are also new features, some of which may slow things down. This the natural balance in software development, but in the end, what is the net effect on performance from one version to the next?

The benchmark

We need a good benchmark to produce good data, but what do we measure? Let's assume the most common operations are starting OpenOffice.org, opening a Writer document, scrolling from top to bottom using the down arrow, exporting the document, and closing both the document and OpenOffice.org.
