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

NAME
     nnffssiioodd - local NFS asynchronous I/O

SYNOPSIS
     nnffssiioodd [-nn numthreads]

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

     nnffssiioodd 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 nnffssiioodd command simply sets the configura-
     tion limit.

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

     The options are as follows:

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

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

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

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