I disagree Rashmin. We did measurements with 64 bytes packets: the Linux
kernel of the guest is the bottleneck, so the vmxnet3 PMD helps to
increase the packet rate of the Linux guests.
PMD helps within guest for packet rate until you rich (of course) the
bottleneck of the host's vSwitch.
In o
Vincent, I agree with your explanation that when you move to PMD from regular
interrupt based driver, you would definitely get better performance of a Linux
guest until you reach the bottleneck of the vSwitch. But I said "optimal
performance benefit having PMD" which is only possible if vmxnet3
