For NFS mounts, parameters are: - Solaris : TCP (r/w)size=32768 a big write = 6s - FreeBSD mount : UDP 8192 6s - FreeBSD amd : TCP 8192 12s!!!! This third setting is very slow, even if is TCP. My answer: using defaults parameters with amd: opts:=rsize=32768,wsize=32768,vers=3,proto=tcp -- Jacques Beigbeder | Jacques.Beigbeder@ens.fr Service de Prestations Informatiques | http://www.spi.ens.fr Ecole normale supérieure | 45 rue d'Ulm |Tel : (+33 1)1 44 32 37 96 F75230 Paris cedex 05 |Fax : (+33 1)1 44 32 20 80 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
