nfsiod

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

NAME

     nfsiod -- local NFS asynchronous I/O

SYNOPSIS

     nfsiod [-n num_threads]

DESCRIPTION

     nfsiod is deprecated.  See nfs.conf(5) for NFS configuration info.

     nfsiod controls the maximum number of asynchronous I/O threads used for NFS mounts.  Historically, it has consisted of a daemon that never
     exits.  However, asynchronous I/O requests are now serviced by threads launched on demand in the kernel and the nfsiod command simply sets
     the configuration limit.

     Having asynchronous I/O threads improves performance but is not required for correct operation.

     The options are as follows:

     -n      Specify maximum number of asynchronous I/O threads to be used.

     If no maximum is specified, nfsiod displays the current value.  The default value is 16.  A client should allow enough threads to handle its
     maximum level of concurrency.

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

SEE ALSO

     nfs.conf(5), mount_nfs(8), nfsstat(1)

HISTORY

     The nfsiod utility first appeared in 4.4BSD.  It's use was deprecated in Darwin 9.
