Re: [ovs-discuss] OVS-DPDK giving lower throughput then Native OVS

So is there any way to have TSO work with OVS-DPDK? Are there any patches which can be applied? Because I followed this Intel page and the author was able to get the 2.5x higher throughput for OVS-DPDK as compared to native OVS.

Re: [ovs-discuss] OVS-DPDK giving lower throughput then Native OVS

I think the reason of lower throughput in the scenario of OVS-DPDK is that TSO(GSO)& GRO are not supported in OVS-DPDK. So the packets between the VMs are limited to the MTU of the vhostuser ports. And the kernel based OVS supports TSO(GSO), the TCP packets can be up to 64KB, so the
