NAME
       nfsiod -- local NFS asynchronous	I/O server

SYNOPSIS
       nfsiod [-n num_servers]

DESCRIPTION
       The  nfsiod  utility  controls  the  maximum  number  of	 nfsiod	kernel
       processes which run on an NFS client machine  to	 service  asynchronous
       I/O  requests  to  its server.  Having nfsiod kernel processes improves
       performance but is not required for correct operation.

       The option is as	follows:

       -n      Specify how many	processes are permitted	to be started.

       Without an option, nfsiod displays  the	current	 settings.   A	client
       should  allow enough number of processes	to handle its maximum level of
       concurrency, typically four to six.

       If nfsiod detects that the running kernel does not include NFS support,
       it will attempt to load a kernel	 module	 containing  NFS  code,	 using
       kldload(2).   If	this fails, or no NFS module was available, nfsiod ex-
       its with	an error.

EXIT STATUS
       The nfsiod utility exits	0 on success, and >0 if	an error occurs.

SEE ALSO
       nfsstat(1), kldload(2), nfssvc(2), mountd(8), nfsd(8), rpcbind(8)

HISTORY
       The nfsiod utility first	appeared in 4.4BSD.

       Starting	with FreeBSD 5.0, the utility no longer	 starts	 daemons,  but
       only serves as a	vfs loader and sysctl(3) wrapper.

FreeBSD	14.3		       December	26, 2009		     NFSIOD(8)
