Process I/O View
Function:
To display the I/O performed by each process.
Description:
This view displays a horizontal bar graph and numeric values showing the bytes of I/O completed by each process on a per second basis. This statistic includes all reads and writes, regardless of the device being accessed.
As CPUs increase in speed, it is the amount of I/O performed that primarily determines a system's overall performance. Consequently, a program that monopolizes the system's I/O resources can dramatically impair system speed.
You can use the
Format
,
Row
Selection
menu option to display only those processes whose I/O value exceeds a certain threshold. Alternatively, you may use the
Process Statistics By User View
to see which users are dominating the I/O load.
