If you are still using that,
the performance might depend on the NUMA node used.
There was a placement bug, and the fix [1] has been merged just before 18.10.

Subject: Re: [vpp-dev] ip4-load-balance

CSIT is measuring roughly 12mpps on HSW.
When I measure with an equivalent system I get 10.5mpps on HSW.

What I am finding is that DPDK is more efficient on CSIT HSW.

CSIT
Graph Node                      Clocks/Vector
dpdk-input                      6.07e1
TenGigabitEtherneta/0/0-tx      4.09e1

My System
dpdk-input                      8.30e1
TenGigabitEthernet83/0/1-tx     5.51e1

So between TX and Input, I am burning an extra 30 Clocks per vector.
That ends up being the essential difference between 10.5mpps and 12mpps.

I tried this with both binaries I built myself and the binaries in package 
cloud, and I get the same result.

Any clues as to what might causing the delta?
(I verified that my system setup was equivalent to CSIT)
