Use of READDIRPLUS operations

In NFS Version 3, file handle and attribute information is returned along with directory entries via the READDIRPLUS operation. This relieves the client from having to query the server for that information separately for each entry, as is done with NFS Version 2, and is thus much more efficient.

However, in some environments with large directories where only the information of a small subset of directory entries is used by the client, the NFS Version 3 READDIRPLUS operation might cause slower performance. In such cases, the nfs_v3_server_readdirplus option of the nsfo command can be used to disable the use of READDIRPLUS. But, this is not generally recommended because it does not comply with the NFS Version 3 standard.
