[dpdk-dev] CloudNetEngine vSwitch boosts performance

[Jun Xiao]

CloudNetEngine vSwitch boosts performance for both NFV and cloud use cases in technical preview update 3.For the details, please refer to http://cloudnetengine.com/en/blog/2015/09/05/cloudnetengine-vswitch-boosts-performance-cloud-an/
One key update:- CNE vSwitch is over 65% better than OVS-DPDK for small packet size traffic. (It's about 10-20% advantage in technical preview update 2)
Again, thanks for all the contributions to make DPDK as such a great foundation!Jun Xiaowww.cloudnetengine.com

The issue is largely philisophical.  We shouldn't need to define the type of bus
a driver is on in the init structure of a pmd.  Instead we should register it
dynamically during pmd initalization

As you note, ennumerating the bus type (ie. PCI/USB/etc) is a step in the right
direction, but it would be better to register that dynamically than to encode it
in the data structure

Closed and Open Source products based on DPDK are encouraged.
It is nice to announce new stuff, but please do it only once.
This mailing list focus on DPDK development discussions, i.e. drivers and algorithms.
Thanks for understanding
