Forgot to mention, your config have enabled gso on tap interface while is not
enabled on dpdk interface.
Either enable it on dpdk interface if the underneath vhost device supports it.
or, disable it from tap interface too.
In case of vpp native virtio:
create int virtio 0000:00:08.0 gso-enabled

Please add following to dpdk stanza in startup.conf
“DPDK { dev 0000:00:08.0 { tso on } enable-tcp-udp-checksum }”
Or else try VPP native virtio without using dpdk:
create int virtio 0000:00:08.0

Hi Mohsin,
Please see below:
Can you please share the numbers you are getting?
Without VPP, I get 5Gbps. With VPP I get ~2Gbps.
And also please share the output of:
sh hardware
sh tap
sh threads
sh cpu
Please see in the attachments.
Thank you.
