X-BeenThere: dev@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: patches and discussions about DPDK List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 20 Jan 2015 18:41:27 -0000 Introduced division of whole 256 child transition enties into 4 sub-groups (64 kids per group). So 2 groups within the same node with identical children, can use one set of transition entries. That allows to compact some DFA nodes and get space savings in the RT table, without any negative performance impact. >>From what I've seen an average space savings: ~20%.
