Hi, Numbers are pretty low, but it’s hard to say just from those what might be wrong. So let’s try to clarify some things: - what vpp version are you running, how many workers and what’s the config? - what’s the vcl config? Are you you using something similar to the one here [1]? - I’m not familiar with that server, is it a dual socket and what type of nic is it using? - if it’s a dual socket, are you pinning vpp’s and nginx’s workers to the nic’s numa? See “show hardware” in vpp for the nic’s numa. Make sure vpp’s and nginx’s workers do not overlap.
Also, any particular reason why you’re running linux tests for 30s and vpp tests for 2m? Are the two ips on the same server?
