sockperf/packet-tp-tcp
sockperf TCP throughput benchmark sweeping message size.
Benchmark Profile
Type: Micro
Kernel subsystem: Networking, TCP sockets, softirq path
Coverage: Directly measured
Topology: Two roles: client, server; multi-node preferred
Overview
Measures maximum TCP throughput between a client and server node using sockperf under-load mode. Sensitive to TCP throughput, window scaling, and network driver performance.
