ip_squeue_fanout

Description

Determines the mode of associating TCP/IP connections with squeues

A value of 0 associates a new TCP/IP connection with the CPU that creates the connection. A value of 1 associates the connection with multiple squeues that belong to different CPUs. The number of squeues that are used to fanout the connection is based upon ip_soft_rings_cnt.

Range

0 or 1

When to Change

Zone Configuration

This parameter can only be set in the global zone.

Commitment Level

Unstable
