�� rsize � wsize. �� man nfs:

rsize=n The number of bytes NFS uses when reading files from an NFS server.
The default value is dependent on the kernel, currently 1024 bytes. (However, throughput is improved greatly by asking for rsize=8192.)

wsize=n The number of bytes NFS uses when writing files to an NFS server. The default value is dependent on the kernel, currently 1024 bytes. (However, throughput is improved greatly by asking for wsize=8192.)
