biod(8nfs)
NAME
biod − Start NFS asynchronous block I/O daemons
SYNTAX
/etc/biod [ndaemons]
DESCRIPTION
The biod daemon starts the specified number of asynchronous block I/O daemons. The ndaemons argument tells biod how many asynchronous block I/O daemons to start. The biod daemon is only useful to NFS clients. This command is used by NFS clients to perform read-ahead and write-behind of remote file system blocks. Like the nfsd() daemon, biod is normally invoked at boot time via the /etc/rc.local file.
EXAMPLE
/etc/biod 2 /* start two biod daemons */
