I take it these are Windows servers? I only ask because Compaq's Tru64 wouldn't need Oracle's Cluster File System.

But in any case: define "slow". As far as I can tell, the CFS for Windows is optimized for Oracle's access only. Trying to save a Word document on it, for example, is indeed slow. But the RAC runs fine.

Are you saying your RAC is suffering from I/O performance issues? Or just that when you play around with the shared disk via Explorer or some other non-Oracle application, you feel it's slow?
