Hi all
I have a question about a performance in a specific use case, and any
suggestions how to improve it. Use case:
Host runs Fedora 23, with kernel 4.4, ovs 2.7.2 and dpdk 16.11. There are
few interfaces: first one does not support DPDK, all others support it.
Tested topology:
port 1 ---> ovs
Folks,
I have configured ovs-dpdk to replace sriov deployment for bonding
support. everything good but somehow as soon as i start hitting
200kpps rate i start seeing packet drop.
I have configured CPU isolation as per documentation to assign a
dedicated pmd thread. I have assigned 8 dedicated PMD

Thank you for reply kevin,
I do have a multi queue configuration, as you can see following. Let
me tell you what tools I am using for traffic generation. We run VoIP

Hi Everyone,
I would greatly appreciate any input.
The setting that i am working with is a host with ovs-dpdk connected to a
VM.
What i see when i do performance test is that after about a minute or two
suddenly i have many drops as if the cache was full and was dumped
improperly.

I tested ovs-dpdk(compiled using ovs 2.6.1) under openstack ocata, and I found
the performance is low.
Can someone give me some suggestions?
iperf3 througput test between 2 VMs on the same compute node gives bandwidth:
6.82 Gbps. Intel 82599ES 10-Gigabit SFI/SFP+ NICs with igb_uio are used.
Hi,
I have been experimenting with OVS DPDK on 1G interfaces. The system has 8
cores (hyperthreading enabled) mix of dpdk and non-dpdk capable ports, but
the data traffic runs only on dpdk ports.
DPDK ports are backed by vhost user netdev and I have configured the system

Hello!
I am using OVS with DPDK in OpenStack. This is RDO+TripleO deployment with the
Train release. I am trying to measure the performance of the DPDK compute node.
I have created two VMs [1], one as a DUT with DPDK and one as a traffic
generator with SR-IOV [2]. Both of them are using Pktgen.
Hi Onkar,
Thanks for your email. Your setup isn't very clear to me, so a few
queries in-line.

Hi Onkar,
Thanks for shedding some light.
I don't think your difference in performance will have to do your
OvS-DPDK setup. If you're taking the measurements directly from the
iperf server side you'd be going through the "Internet". Assuming you
don't have a dedicated connection there, things lik
Hi Tiago,
Sure. I'll try that.

Hi,
We figured out that the packet processing appliance within VM (which reads
from raw socket on the dpdk vhost user interface) requires more packets per
second to give higher throughput. Else its cpu utilization is idle most of
the times.
We increased the "tx-flush-interval" from default 0 to 5
Hi,
I managed to solve this performance issue. I got improved performance after
turning off the mrg_rxbuf and increasing the rx and tx queue sizes to 1024.
Thanks,
Onkar

Hi all,
I am able to get expected performance using ovs dpdk on a single socket
system.
But on a system with 2 NUMA nodes, the throughput is less than expected.
The system has 8 physical cores each socket with hyperthreading enabled. So
total 32 cores.
Only one physical 10G interface is being us
