About ixgben's QPair issue

[MASATOSHI_T]

Hello.

The following event was listed in the VMware known issues, has it been resolved with the latest ixgben?

VMware has told me to contact the hardware vendor regarding the driver.

The latest version of the driver is ixgben 1.11.4.0.

"Networking Issues
Reduced throughput in networking performance on Intel 82599/X540/X550 NICs
The new queue-pair feature added to ixgben driver to improve networking performance on Intel 82599EB/X540/X550 series NICs might reduce throughput under some workloads in vSphere 7.0 as compared to vSphere 6.7.

Workaround: To achieve the same networking performance as vSphere 6.7, you can disable the queue-pair with a module parameter. To disable the queue-pair, run the command:

# esxcli system module parameters set -p ""QPair=0,0,0,0..."" -m ixgben

After running the command, reboot."
