The 'parallelism' only applies indirectly. Here it limits the max no of save streams which are allowed to be opened at a certain time.
For RMAN backups it is the number of channels you open/allocate. The more the better, depending on your backup scenario. As I remember, the max. is 256 for Oracle so this alone would never drive NW into a bottleneck position.
