Hi All,
I was trying to measure maximum PPS handled by vpp.I have installed ubuntu
16.04 on my server.I have followed vpp recommended bios settings.

My vpp model has 1 main thread and 1 worker thread.I was not able to get
more than 6Mpps .After 6 Mpps i can see the rx_miss counters in vpp stats.

I thought i can get entire 15 Mpps traffic from it.Can someone please
suggest what could be the reason here that i am getting only 6 Mpps traffic
with this.Or this could be expected numbers?
Thanks,
rahul
