I'm getting pretty good performance with these settings: fstab on nfs mount client: naked:/mnt/share/ftp /mnt/nfs/ftp nfs defaults,auto,soft,rsize=8192,wsize=8192,bg,posix,nosuid,intr,tcp 0 0
exports on nfs mount host: /mnt/share/ftp 192.168.x.xxx(root_squash,rw,async,secure,nohide,anonuid=65534,anongid=65533) Note that the NFS host has nfs over tcp enabled, which (AFAIK) makes it much faster. Barring that, if you do the same thing with SMB, are the results similar?
