Re: [dpdk-dev] [PATCH v3 0/5] vhost add vectorized data path

Hi All, Performance gain from vectorized datapath in OVS-DPDK is around 1%, meanwhile it have a small impact of original datapath. On the other hand, it will increase the complexity of vhost (new parameter introduced, prepare memory information for address translation). After weighed the procs

[dpdk-dev] [PATCH v3 0/5] vhost add vectorized data path

Packed ring format is imported since virtio spec 1.1. All descriptors are compacted into one single ring when packed ring format is on. It is straight forward that ring operations can be accelerated by utilizing SIMD instructions. This patch set will introduce vectorized data path in vhost librar
