Hi Danny,
My response is inline below.

Hi Tom, Karl,
In the last “Todo List” page, there is RFC2544 0% packet loss test
item, do you want to measure the min/max latency as well?
Is your question particularly about vhost-user testing?
Also, I am interested in why you brought up latency. Are you doing your
own latency testing in conjunction with your nsh-sfc work and do you
think we need to do latency in CSIT as well in testing nsh-sfc perf on
vhosts?
I will let Karl answer as to the testing he has done and is doing.
However, in fd.io CSIT, the latency for vhost-user results are here:

Jan,
I have answered below but am forwarding this to Karl who performed the
testing to get the exact answers.

Hi Thomas,
Thanks for these interesting measurements. I am not quite sure I
fully understand the different configurations and traffic cases
you have been testing:
·*/[Zhou, Danny] /*ToDo you vary the number of vhost-user queues
to the guest and/or the number of RX queues for the phy port?
These are vhost user queues. Because OVS and/or VPP is running in the
host.
·Did you add cores at the same time you added queues?
Yes
·When you say flows, do you mean L3/L4 packet flows (5-tuples) or
forwarding rules/flow rules?
These are L2 matches.
·When you e.g. say N flows (srcip, dstip) do you mean matching on
these fields, modifying these fields or both
Would it be possible to provide the exact VPP and OVS
configurations that were used (ports, queues, cores, ports,
forwarding rules/flows)?
Thanks, Jan
Here are test results on VPP 17.01 compared with OVS/DPDK 2.6/1611
performed by Karl Rister of Red Hat.
This is PVP testing with 1, 2 and 3 queues. It is an interesting
comparison with the CSIT results. Of particular interest is the
drop off
on the 3 queue results.
