Hi all, ok, I've searched far and wide, but I have to ask the FreeBSD gurus about it... I'm using a Netapp NFS server to serve up content to FreeBSD clients, and I am seeing terrible write performances. I've turned on these in the rc.conf file : nfs_client_enable="YES" nfs_client_flags="-n 4" nfs_server_enable="YES" rpc_lockd_enable="YES" rpc_statd_enable="YES" nfs_bufpackets=8 and I've got these in the sysctl.cnf file : kern.maxfiles=32768 net.inet.tcp.keepidle=3600 net.inet.tcp.sendspace=65536 net.inet.tcp.recvspace=65536 net.inet.tcp.slowstart_flightsize=2 kern.ipc.somaxconn=16384 kern.ipc.shmall=65536 kern.ipc.shmmax=268435456 kern.ipc.nmbclusters=32768 I'm using 5.3-RELEASE on a dual AMD Opteron machine. I guess my question is, how do I make NFS writes fly ??? The reads seem to be pretty good. I know that the settings on the netapp are per their settings... Thanks, Tim.
