Re: [dpdk-dev] dev@DPDK Hackathon Proposal

Hi Przemek/Thomas,
   Thanks for the info. But when I am using the latest ovs and the DPDK2.0 the performance I am getting through the ovs switch is far less than non dpdk. 
I can send more info if you need. 
I am using dpdkvhost0 and dpdkvhos1 interfaces that are based on vhost_cuse to interact with VM. Is there any post that I can refer to see what I may be missing ?
Currently these are my tasks
1. Measure throughput with Just OVS on Host only == completed (600,000 pps) *No Flow control
2. Measure throughput with OVS+DPDK on Host only == completed (6.4 Mpps)
3. Measure throughput on Guest spunup using QEMU with OVS bridge on Host == completed (240,000 pps)
4. Measure throughput on Guest spunup using QEMU with OVS DPDK on Host == Having issues with perf just getting 60,000 pps
5. Measure throughput on Guest spunup using Openstack with just OVS on Compute node == completed (60,000 pps)
6. Measure throughput on Guest spunup using Openstack with OVS DPDK on Compute node. I can use the info provided by you and see if I can get this running ??
Regards,
Ravi..

Hi Ravi,

 Kilo release of Openstack  allows to use ovs-dpdk with vhostuser. 
Nova includes vhost-user vif driver, and for neutron we have a mechanism driver and agent in stackforge project :
https://github.com/stackforge/networking-ovs-dpdk

The neutron part is hosted on stackforge because of vendor decomposition  going on in neutron.
The contains a devstack plugin and instructions on how to setup the node.

Let me know if you need more information.

Regards
Przemek
