Bug Description
R3.0.2.0 Build 35 Ubuntu 14.04 Kilo multi-node setup
In this setup, an ixia port is sending traffic to another ixia port via a vrouter VM
The VM does routing for these packets
So, 1 packet from Ixia results in 4 flows overall on the compute node.
In such a setup, sent 13000 pps traffic (i.e 52K flows per sec) without aging, upto 2M flows in total.
Here, the avg latency for these packets was ~29 msec, max being ~200 ms
With aging(10 sec aging interval), the avg latency for these packets was ~28 msec, max being ~300 ms
Praveen is looking at optimizing the latency numbers
