Yes if you have the hardware that supports it. i.e. pci-e 40G/100G interface. it eliminates the user <> kernel mode transitions which are expensive transitins

Hi

Yes as the QLogic FastLinQ 3400/8400 SR-IOV and I/O pass-through functionality for Ethernet network adapters provides RSC capabilities along with SR-IOV, which improves network throughput and CPU efficiency giving  greater VM density/host and increased network bandwidth on the host and guest VMs on Servers running hypervisors—such as Microsoft Windows Server2012/2012 R2 Hyper-V, RHEL 6.5 KVM, SLES 11.3 XEN, Citrix® XenServer 6.2, and VMware® ESXi 5.5
