Sara,
You need qemu 2.8.0 or later for the rx_queue_size option to work.

Fyi
When i launch another image (not based on the clear-linux-kvm) - i'm achieving
good performance (exactly like ovs-dpdk - which is expected in single flow/mac )
any idea why ?
this is the launch cmdline: [anyway i cant fi

Hi John and Steven
setting this in the startup config didnt help
vhost-user {
coalesce-frame 0
}

I'm using ping -f for latency and iperf3 for pps testing.
later i'll run pktgen in the vm's

Hi Sara,
Can you also send the results from show hardware and show interfaces?
What are you using to test your performance.

Hello
i setup 2 vm connected to VPP as per the guide :
https://wiki.fd.io/view/VPP/Use_VPP_to_connect_VMs_Using_Vhost-User_Interface
The performance looks very bad very low pps and large latencies
udp pkt size 100B - throughput 500Mb
average latency is 900us
i have 2 PMDs threads (200% cpu) in
15 matches
