[dpdk-dev] Maximum possible throughput with the KNI DPDK Application

Hi all

I've been playing the with DPDK API to send out packets using the l2fwd app
and the Kernel Network Interface app with a single Intel 82599 NIC on an
Intel Xeon E5-2630

With the l2fwd application, I've been able to achieve 14.88 Mpps with
minimum sized packets.
However, running iperf with the KNI application only gives  me only ~7Gb/s
peak throughput.

Has anyone achieved the 10Gb/s line rate with the KNI application?
Any help would be greatly appreciated!

Thanks!
Malveeka
