40.Sh SYNOPSIS
41.Nm
42.Op Fl n Ar num_servers
43.Sh DESCRIPTION
44.Nm Nfsiod
45runs on an
46.Tn NFS
47client machine to service asynchronous I/O requests to its server.
48It improves performance but is not required for correct operation.
49.Pp
50Unless otherwise specified, a single server is started.
51.Pp
52The options are as follows:
53.Bl -tag -width indent
54.It Fl n
55Specify how many servers are to be started.
56.El
57.Pp
58A client should run enough daemons to handle its maximum
59level of concurrency, typically four to six.
60.Pp
61If
62.Nm
63detects that the running kernel does not include
64.Tn NFS
65support, it will attempt to load a loadable kernel module containing
66.Tn NFS
67code, using
68.Xr kldload 8
69by way of
70.Xr vfsload 3 .
71If this fails, or no
72.Tn NFS
73KLD was available,
74The
75.Nm
76utility exits with an error.
