Are you sure you updated qemu ?

All the CSIT changes should be now part of oper-161024. Patch to use this branch in VPP was merged yesterday https://gerrit.fd.io/r/#/c/3553/ @Pierre: Can you please rebase your commit https://gerrit.fd.io/r/#/c/2922/ and recheck? Please report to csit-dev. If there is requirement for higher version than 2.5.0 I suggest to open Jira ticket to CSIT. Thank you.

Do you do the same with 'indirect descriptors' ? They are supported by VPP since september or so. The issue with these zillions ways a buffer may be forwarded is that we only know what mode is enabled or disabled, but you never know exactly what is happening for real. Using indirect descriptors, I got VPP doing 0% loss 10Mpps (5Mpps each way). And the setup was stricter than yours as VPP had only 2 threads on the same core. You may also want to try 'chrt -r' on your working processes. This improves scheduling real-time properties.

Your results seem close to consistent with VPP's CSIT testing for vhost for 16.09 but for broader visibility, I am including some people on the VPP team, Damjan who is working on multi-queue etc. (I see that there were some perf related patches merged in vhost that might help since 16.09.) and Maciek who works in the CSIT project and has done the testing of VPP. I want to open up the discussion WRT to the following: 1, Optimizing for maximum vhost perf with vpp including vhost-user multi-queue. 2. Comparision with CSIT results for vhost. Following are two links for CSIT 3. Statistics: 4.
