sockperf/echo-lat-udp
sockperf UDP ping-pong latency benchmark sweeping message size.
Benchmark Profile
Type: Micro
Kernel subsystem: Networking, UDP sockets, scheduler
Coverage: Directly measured
Topology: Two roles: client, server; multi-node preferred
Overview
Same as echo-lat-tcp but using UDP. Measures raw UDP round-trip latency without TCP overhead. Sensitive to kernel UDP receive and send paths.
