It is very well documented and you can then inspect the best way to benchmark VPP etc. Ray K On 24/01/2018 21:23, Li, Charlie wrote: > 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).
