I came up with these numbers in an attempt to get client NFS access speeds up to par with SMB or CIFS connections: nfsserver:/data /data nfs fsv3,intr,rdirplus,-r=32768,-w=32768,rw On the NFS server I have in my /etc/sysctl.conf: vfs.nfs.async=1 Also make sure you have enough nfsiod running on the client to service requests, and enough nfsd on the server to service the clients.
