There is some format issue with the ascii chart of the tx ring. Update that chart. Sorry for the trouble. On 9/4/2015 4:25 PM, Xie, Huawei wrote: > Hi: > > Recently I have done one virtio optimization proof of concept. The > optimization includes two parts: > 1) avail ring set with fixed descript

Hi: Recently I have done one virtio optimization proof of concept. The optimization includes two parts: 1) avail ring set with fixed descriptors 2) RX vectorization With the optimizations, we could have several times of performance boost for purely vhost-virtio throughput. Here i will only cover
