Nfsiod runs on an NFS client machine to service asynchronous I/O requests
to its server. It improves performance but is not required for correct
operation.
Unless otherwise specified, a single server is started.
The options are as follows:
-n Specify how many servers are to be started.
A client should run enough servers to handle its maximum level of concur-
rency, typically four to six. Each server runs as a separate thread
within the nfsiod process.
The nfsiod utility exits 0 on success, and >0 if an error occurs.
