Hi Kunal,
Yes, it might be worth looking into ip and tcp csum offloads.
But given that mtu ~ 9kB, maybe look into forcing tcp to build jumbo frames,
i.e., tcp { mtu 9000 } in startup.conf. It’ll be needed on both ends and I’m
assuming here network between your two vpp instances supports 9k mtu.
Regards,
Florin
