Hi Charlie,
Please see this preso and associated paper from Kubecon - it is a pretty
comprehensive guide on where to start.

Also consider replicating the CSIT test environment locally.
It is very well documented and you can then inspect the best way to
benchmark VPP etc.

Hi All,
I am looking for some guidance on how to tune the VPP performance, specifically
how to tune the IP Forwarding performance for small packets.
Appreciate if someone can point me to some documents or online resources on
this topic.
My setup is simple, just an XL710-QDA2 NIC card with two 40G ports and VPP is
configured to forward IP traffic between the two ports.
Basically I am using the default /etc/vpp/startup.conf (with PCI device address
and core numbers modified). The throughput for bi-directional traffic with
small packets is far below line rate. Throwing more cores does not seem to
improve.
Regards,
Charlie Li
