There are things you can do to tune GFS, most of them referenced in the FAQ or in posts to this lists. It's might be that you'll get bigger improvements by tuning the app to work better with GFS though, i.e. to avoid operations that are known to be expensive over GFS. Can you give us some idea of how the application accesses & uses the data in the GFS file system?
