+Maciek Konstantynowicz CSIT (mkonstan) +vpp-dev +Damjan Marion (damarion) Karl, Thanks! 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. Tuning suggestions: Following are some CSIT results: compiled 16.09 results for vhost-user: https://wiki.fd.io/view/CSIT/VPP-16.09_Test_Report#VM_vhost-user_Throughput_Measurements Latest CSIT output from top of master, 16.12-rc0 https://jenkins.fd.io/view/csit/job/csit-vpp-verify-perf-master-nightly-all/1085/console --Tom On 10/21/2016 04:06 PM, Karl Rister wrote: Hi All Below are updated performance results for OVS and VPP on our new Broadwell testbed.
