Distribute files to different file systems to use the combined bandwidth of the file systems assuming each file system uses an independent physical disk sub-system. Distributing files to different file systems can increase performance on a grid that uses either a shared file system or symmetric multiprocessing (SMP).
For optimal I/O bandwidth choose a file system that distributes files across multiple storage devices. If you use a clustered file system, distribute the files between servers. If possible, place the source, target, and cache files on different storage devices.
