In otherwords don't just mount /export/home but mount: /export/home/user1 /export/home/user2 .... /export/home/userN Each mount is handled by a different process, each process can only handle a specific number of read/write requests - so the more NFS processes you throw at it, the more simultaneous read/writes you can do. -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/ TriLUG PGP Keyring : http://trilug.org/~chrish/trilug.asc
