Link time performance
When developing console games, linking becomes an inevitable iterative process as changes are made and bugs are fixed. Whilst the C++ file may only be re-compiled once, for example after the file is modified, all of the intermediate files are re-linked, thereby generating the final executable, in every build. Over the course of the development life cycle this can mean having to re-link a game many thousands of times before it finally reaches the consumer. Reducing the overall time each link takes makes a significant impact to the games development process.
