I've got a very poor performance - compared to normal OVS (i.e. no DPDK).=20 For example - TCP jumbo pkts throughput: normal OVS ~ 10Gbps , OVS-DPDK 1.= 7 Gbps. This can be explained as follows:=20 veth is implemented in kernel - in OVS-DPDK data is transferred from veth t= o user space while in normal OVS we save this transfer Is there any other device to connect to namespace ? something like vhost-us= er ? I understand that vhost-user cannot be used for namespace=20 Best Regards avi
