Public bug reported:
We recently tested the openvswitch-agent flow installation performance,
we have following two results:
1. the AGENT_RES_PROCESSING_STEP is 100 (default)
We can see the 4296 OpenFlow rules are installed in 20s.

So we can say maybe we should increase the trunk (step) size for the
ovs-ofctl bundle installaion. We do not want to add a fixed value
because the vswitchd may be in high pressure according to your
deployment, the flow install performace may not be as good as you
expected. So we could add a config option for users, they can tune the
size for their cloud based on the load of the agent, vswitchd and cpu
usage and so on.

- So we can say maybe we can increase the trunk (step) size for the ovs-ofctl
bundle installaion.
- We do not want to add a fixed value because the vswithd may be in high
pressure according to your deployment, the flow install performace may not be
as good as your excepted. So we can add a config option for users, they can
tune the size for their cloud based on the load of the agent, vswitchd and cpu
usage and so on.

[L2][scale] add a trunk size config option for bundle flow install
Status in neutron:
New
Bug description:
We recently tested the openvswitch-agent flow installation
performance, we have following two results:
1. the AGENT_RES_PROCESSING_STEP is 100 (default)
We can see the 4296 OpenFlow rules are installed in 20s.

So we can say maybe we should increase the trunk (step) size for the
ovs-ofctl bundle installaion. We do not want to add a fixed value
because the vswitchd may be in high pressure according to your
deployment, the flow install performace may not be as good as you
expected. So we could add a config option for users, they can tune the
size for their cloud based on the load of the agent, vswitchd and cpu
usage and so on.
