Starting in OVS 2.2, there will be a configuration parameter to set the default value. However, this knob is not really intended to be used by users and will probably get removed when we get more experience choosing a good value. *Why the concern? * This should really be an implementation detail if the system is working properly.
=> I want to test performance there are many flows in datapath. Does OVS 2.0 have 1.5 secs for timeout of flow entries in datapath? Yes. Also flow set up rate can impact how flows are cached. => Does "how flows are cached" mean insert datapath or is there another cache in OVS?
