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.
