It is a Westmere if I am correct. So,use UIO.

My experience is that the CPU isn't as an important part of the platform
as the chipset. IOW, VFIO requires full IOMMU

You are right, under some conditions UIO is faster, VFIO provides
safety. The best solution is a PMD

Thank you very much.
My cpu is "Intel(R) Xeon(R) CPU E5620 @ 2.40GHz"

I have test the VFIO driver and IGB_UIO driver by l2fwd for many times. I find
that the VFIO driver?s performance is not better than the IGB_UIO.
Is something wrong with my test? My test is as follow:
1. bind two 82599 ether to VFIO ./tools/dpdk_nic_bind.py -b vfio-pci
