Configure High Performance Mode

Before You Begin

The following steps are required to operate PVS in High Performance mode. Alternatively, a user with administrative privileges can enable High Performance mode via the UI.

You must have a High Performance Activation Code in order to run PVS in High Performance mode.

PVS uses multiple cores to process packets received from the monitored interfaces. These cores are known as worker cores, and the default number of worker cores is 8. This number can be changed using the configuration parameter Number Of Worker Cores.

Note: If you set the Number Of Worker Cores parameter to 0, PVS automatically changes the value to the minimum number of worker cores needed to run PVS in High Performance mode.

For example, suppose you have 20 available logical cores. Four of those cores are used by the system for internal processing and the kernel. If you want to use the 16 available cores for PVS, then you may change the value for the parameter Number Of Worker Cores to 16.


  1. Stop PVS with the following command:

    # service pvs stop

  2. Enable High Performance mode with the following command:

    /opt/pvs/bin/pvs --config "Enable High Performance Mode" "1"

  3. Confirm that the management network interface is different from the monitoring network interface that you configured initially.

    Note: If the configured monitored interface has bound IPv4 addresses, you cannot complete the Quick Setup Wizard to configure PVS because no usable NICs appear in the Monitored Network Interfaces list.

  4. Start PVS with the following command:

    # service pvs start
