Per the Vmware release notes:
I'm running 7.0 Update 2 . Did they fix it and remove the command? The release notes don't show it as being resolved.
When I try the suggested command below, I get the following response: Error: Unknown command or namespace sytem module parameters setNetworking 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
esxcli system module parameters set -p "QPair=0,0,0,0..." -m ixgben
