I/O Management

These settings allow you to optimize the I/O priority of specific processes, so that processes which are contending for disk and network I/O access do not cause performance bottlenecks. For example, you can use I/O Management settings to throttle back a disk-bandwidth-hungry application.

The process priority you set here establishes the “base priority” for all of the threads in the process. The actual, or “current,” priority of a thread might be higher (but is never lower than the base). In general, Windows give access to threads of higher priority before threads of lower priority.

I/O Priority

Enable Process I/O Priority. Enables manual setting of process I/O priority.

To add a process to the I/O priority list

  1. Click Add and type details in the Add Process I/O Priority dialog.
  2. Click OK to close the dialog.
  3. Click Apply to apply the settings. Process I/O priorities you set here take effect when the agent receives the new settings and the process is next restarted.

Process Name. The process executable name without the extension. For example, for Windows Explorer (explorer.exe) type “explorer”.

I/O Priority. The “base” priority of all threads in the process. The higher the I/O priority of a process, the sooner its threads get I/O access. Choose from High, Normal, Low, Very Low.

To edit a process I/O priority item
