Tuning I/O resources
Input/output (I/O) is the process
of transferring data from memory to a device, from
a device to memory, or from one device to another.
Most I/O usually occurs between memory and the system's
hard disk drives, though on some multiuser systems,
it might be between the system and terminals connected via the
network or serial lines.
If the speed at which peripheral devices can access and
communicate data to the system is relatively slow, the
may spend most of its time
idle waiting for I/O
asleep until the I/O completes.
The following sections contain information about the monitoring
and tuning of various I/O subsystems:
