Multi-Queue

By default, each network interface has one traffic queue handled by one CPU.

You cannot use more CPU cores for acceleration than the number of interfaces handling traffic.

Multi-Queue lets you configure more than one traffic queue for each network interface.

For each interface, more than one CPU core is used for acceleration.

Note - Multi-Queue is applicable only if SecureXL is enabled (this is the default).

Overview:

• Multi-Queue is enabled by default on all interfaces that use the supported drivers.

• The number of traffic queues on each supported interface is determined automatically, based on:

  • The number of available CPU cores that run CoreXL SND Instances.

  • The limitations of the interfaces and its driver.

• Traffic queues are automatically affined to the CPU cores that runs CoreXL SND Instances.

• Changes in Multi-Queue configuration do not require a reboot.

• You configure Multi-Queue on the command line in the Expert mode.
