Hi We are doing some network experiment and found something that we can't explain well.
We are using qemu+kvm to create a sandbox and use virtio vhost net to setup the network between guest and host. Then we start to send some traffics from host to guest and guest to host. An interesting finding we got is guest to host bandwidth(10Gbps) is much smaller than host to guest bandwidth(40Gbps) and we didn't have any special settings for vhost-net and qemu. So i wanna ask some insights about why we see such performance difference and how we can improve the guest to host network. Thanks Shuo
