+.Sh NAME
+.Nm nfsiod
+.Nd local
+.Tn NFS
+asynchronous I/O server
+.Sh SYNOPSIS
+.Nm nfsiod
+.Op Fl n Ar num_servers
+.Sh DESCRIPTION
+.Nm Nfsiod
+runs on an
+.Tn NFS
+client machine to service asynchronous I/O requests to its server.
+It improves performance but is not required for correct operation.
+.Pp
+Unless otherwise specified, a single server is started.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl n
+Specify how many servers are to be started.
+.El
+.Pp
+A client should run enough daemons to handle its maximum
+level of concurrency, typically four to six.
+.Pp
+The
+.Nm nfsiod
+utility exits 0 on success, and >0 if an error occurs.
+.Sh SEE ALSO
+.Xr nfsstat 1 ,
+.Xr nfssvc 2 ,
+.Xr mountd 8 ,
+.Xr portmap 8
+.Sh HISTORY
+The
+.Nm nfsiod
+utility first appeared in 4.4BSD.
