Similarly I am looking on c ++ std:unorder_mapmap with similar entries . I am just doing lookup with 20 keys aginsts 2k entries and the through put performance dip around <=4gbps using rte_hash when compared to std:unorder_map in 100G line .Is there any way to scale the performance using the rte_hash library... with regards, Rahul
