However, there is no one-size-fits-all The /etc/fstab entry used by my nfs client is {server_ip}:/home/ {server_user}/ {server_path} /home/ {client_user}/ {client_path} I wanted to know the rsize and wsize values rsize=n: NFS サーバからファイルを読み込む際に、 NFS が用いるバッファのバイト数 を指定する。 (1024) wsize=n: NFS サーバにファイルを書き込む際に、 NFS が用い rsize=num and wsize=num — These settings speed up NFS communication for reads (rsize) and writes (wsize) by setting a larger data block size, in bytes, to be transferred at one time. 11. This reduces For instance, suppose you mount your users' home directories from a machine named moonshot, which uses a default block size of 4 K for read/write operations. Recent NFS servers and clients will work out the best value for you and will probably do a better job than you would as well. 2,rsize=131072,wsize=131072 0 0 Why Does The Output of mount Show Smaller rsize and wsize than I Requested?
