       NAME
             biod - NFS daemon

       SYNOPSIS
             /usr/lib/nfs/biod

       DESCRIPTION
             The biod command starts the asynchronous block I/O daemons.
             This command is used on an NFS client to buffer read-ahead and
             write-behind.

       USAGE
             The biod daemons are automatically invoked in run level 3.

             biod uses kernel light weight processes (LWPs) to do the
             asynchronous NFS I/O.  The kernel LWPs are created or deleted
             dynamically, depending on the asynchronous I/O load.  The
             maximum number of LWPs is controlled by the kernel tunables
             NFS_ASYNC_MAX and NFS_MNT_ASYNC_MAX.

             Only a privileged user can start the biod daemons.
