Patch 1 is not an optimization per se, but aimed at eliminating the exporting of internal conntrack infra.
Patch 2 Add RCU support. This is mainly done for performance reasons, but also simplifies the code. Patch 3 Moves the conntrack entry locking to the L4 protocol specific layers. This is done for performance reasons and some memory savings. Patch 4 is mainly for memory savings for the most common cases, but also increases performance for large number of flows (> 100000). Patch 5 is a performance optimization for recirculations. This series starts at v1 although some parts were sent out earlier as a single patch; that is because the earlier series stated that the patch would later be split out and added to, hence that is an implied RFC. Also, this series brings in a couple new improvements not in the original patch. These patches presently include an updated version of the changes for this series https://patchwork.ozlabs.org/project/openvswitch/list/?series=78059 but those parts (approx 20 lines) will be later dropped from this series and handled with the above mentioned series.
