If you threw that much hardware at a Linux system, and then tuned it so that it didn't really care about userspace performance (oh.. say.. by giving the knfsd thread a RT priority ;), and tuned things like the filesystem, the slab allocator and the networking stack to NFS requirements, it probably would be screaming fast too.. ;) --==_Exmh_1105435195_27063P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFB45o7cC3lWbTT17ARAj9LAJ9cNo/eoNx1qgtirkJ1sLpU3eyWMQCgrrD9 2haUKS82M2dgbjQew0sc2II= =Oh23 -----END PGP SIGNATURE----- --==_Exmh_1105435195_27063P-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
