We have execute bunch of tests for receive data with Intel XL710 40GE NIC. We want to achieve wire speed on this platform for traffic capture. But we definitely can't do it. We tried with different versions of DPDK: 1.4, 1.6, 1.8, 2.0. And have not success. We achieved only 40Mpps and could do more. Could anybody help us with this issue? Looks like this NIC's could not work on wire speed :( Platform: Intel Xeon E5 e5 2670 + XL 710. -- Sincerely yours, Pavel Odintsov
