44.Sh SYNOPSIS
45.Nm
46.Op Fl n Ar num_servers
47.Sh DESCRIPTION
48.Nm Nfsiod
49runs on an
50.Tn NFS
51client machine to service asynchronous I/O requests to its server.
52It improves performance but is not required for correct operation.
53.Pp
54Unless otherwise specified, a single server is started.
55.Pp
56The options are as follows:
57.Bl -tag -width indent
58.It Fl n
59Specify how many servers are to be started.
60.El
61.Pp
62A client should run enough daemons to handle its maximum
63level of concurrency, typically four to six.
64.Pp
65If
66.Nm
67detects that the running kernel does not include
68.Tn NFS
69support, it will attempt to load a loadable kernel module containing
70.Tn NFS
71code, using
72.Xr kldload 8
73by way of
74.Xr vfsload 3 .
75If this fails, or no
76.Tn NFS
77KLD was available,
78The
79.Nm
80utility exits with an error.
