Hi, Alejandro, Thanks for you quick response.
>When SRIOV is used by VMs, the slow path will always be faster (and >with lower latency) with DPDK. Yes, I am referring primarily to the SRIOV case in my question, when assigning PCI VF to a VM (most likely QEMU VM) Can you please explain what you mean about slow path in this context ? Not sure the OVS setup is relevant here, it seems (if I understand correctly) that VFIO is more commonly used in OVS setups, so this query is not relevant here (unless you use igb_uio which is less common) According to http://docs.openvswitch.org/en/latest/intro/install/dpdk/ "VFIO is prefered to the UIO driver when using recent versions of DPDK. " Regards, Rami Rosen
