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 is a kernel process which runs on an NFS client
     machine to service asynchronous I/O requests to its server.  It improves
     performance but is not required for correct operation.

     This program controls the maximum number of processes that the kernel
     runs.  Unless otherwise specified, a single server is started.

     The options are as follows:

     -n      Specify how many servers are to be started.

     A client should run enough daemons 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 loadable kernel module containing NFS code,
     using kldload(2) by way of vfsload(3).  If this fails, or no NFS KLD was
     available, nfsiod exits with an error.

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

SEE ALSO
     nfsstat(1), kldload(2), nfssvc(2), vfsload(3), mountd(8), nfsd(8),
     portmap(8)

HISTORY
     The nfsiod utility first appeared in 4.4BSD.
