I've hit a sort of impasse, and I don't know why my changes are making any difference to read/write speeds. The situation: Our office has multiple Linux workstations. They can write 256MB to a home directory (NFS mounted) in ~45 seconds when NFSv3 is enabled, and write the same data in about ~1:30 when I force them to use NFSv2. (I have taken the necessary steps to ensure that disk caching does not befuddle these results, and not changed any other options on the server or client side. Also, the NFS server is running Linux.) When I force NFSv2 on our FreeBSD machines, it writes the data in about ~1:30. When I specify NFSv3, it writes 256MB in about ~1:40! Please note that the settings on the server did not change, and I mimicked the Linux clients' settings in FreeBSD. Does anyone have any experience tuning NFS mounts on FreeBSD machines?=20 --=20 Devin Heckman System Administrator RSSP-IT-NI, UC Berkeley --s9kDAZ2EyO0AcRYa Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) iD8DBQFGXJL7BU328th835IRAk6HAKDE23ofRJjiemEiHmianeCOjXPPJQCgrWQw Bftd6llx9KhinYtaLWB3n50= =j070 -----END PGP SIGNATURE----- --s9kDAZ2EyO0AcRYa--
