The document discusses improving the cold startup performance of OpenOffice.org 3.2. It summarizes the improvements made in OO3.2 including reducing the number of libraries loaded at startup by merging libraries. It then discusses the PE file format and how merging two libraries reduces the number of files opened and amount of data read from disk. Test results showed merging 65 libraries into 10 in OO1.1 reduced the number of libraries loaded at startup from 68 to 24, improving the cold startup time.
