Eric Dumazet 9cd5ef0b8c net: rfs: add sock_rps_delete_flow() helper ... RFS can exhibit lower performance for workloads using short-lived flows and a small set of 4-tuple. This is often the case for load-testers, using a pair of hosts, if the server has a single listener port. Typical use case : Server : tcp_crr -T128 -F1000 -6 -U -l30 -R 14250 Client : tcp_crr -T128 -F1000 -6 -U -l30 -c -H server | grep local_throughput This is because RFS global hash table contains stale information, when the same RSS key is recycled for another socket and another cpu. Make sure to undo the changes and go back to initial state when a flow is disconnected. Performance of the above test is increased by 22 %, going from 372604 transactions per second to 457773.
