NFSIOD(8)		FreeBSD	System Manager's Manual		     NFSIOD(8)

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 concur-
     rency, 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	exits
     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.
