Some things (ie thousands of tiny files) will cause a lot of seeks on the machine to be backed up. If you aren't using attribute spooling then each backed up file also causes a record to be inserted in to the database, which may take time depending on your DB environment.
The 'suggestions' for tuning will be different if you are backing up a few dozen 10GB files versus backing up a million 10kb files.
