Last updated on MARCH 16, 2023

Applies to:

Linux OS - Version Oracle Linux 5.4 and later
Oracle Cloud Infrastructure - Version N/A and later
Linux x86
Linux x86-64

Symptoms

An Oracle Linux system is configured to use network interface card (NIC) bonding.
Having switched the bonding configuration from active-passive to active-active (LACP/TLB/ALB), no significant network performance gain is observed.
Given the concurrent use of two NIC, one expects to realise twice the network performance.

The following compares network throughput of various bonding configurations using the iperf(1) network bandwidth measurement tool.

Iperf stats

Client node execute simple iperf command:

 

Changes

Linux network bonding configuration was reconfigured from active-passive config to active-active - LACP / TLB / ALB
