Hi,
>From my tests vmxnet3 pmd processes packets at a rate of about 1.8Gbps,
while the stock vmxnet3 driver is 20% faster. Is anyone seeing this too?
I based my code on examples/skeleton/basicfwd.c, and I have experimented
with different numbers for RX_RING_SIZE, BURST_SIZE etc. but no much
difference is seen.
The VM is running CentOS 7. dpdk-16.11.2 is used.
Thanks,
Zhao
