Hi,

Do we plan to include the ovn conditional monitoring usage in 2.6.0?
Performance evaluation shows up to 75% reduction of computation at the 
ovn-controller and also a reduction of computation at the server side, 
depending at the spread of the logical networks over the physical hosts. 
(numbers are included in the commit message).

The client side (ovn) of the patch series is still under review: 
http://openvswitch.org/pipermail/dev/2016-August/077007.html

There was also additional work using conditional monitoring, that 
introduced an optimization of flood fill in the ovn-controller to reduce 
the number of hops required to reveal all datapaths:

This optimization can be added on top of the origin patch.

Thanks,
- Liran
