mmtests/sysbench-mutex

sysbench mutex benchmark measuring lock contention and mutex hand-off latency.

Benchmark Profile

Type: Macro
Kernel subsystem: Futex, scheduler, locking
Coverage: Directly measured
Topology: Single role: executer

Overview

Runs the sysbench mutex workload through mmtests to measure lock contention and mutex hand-off costs across thread counts. Sensitive to scheduler wakeups, futex behavior, and lock contention changes.

Fastpath Parameters

Name	Description
config-base	Base mmtests configuration file.
config	Additional mmtests configuration overrides, including SYSBENCHMUTEX_ITERATIONS.
performance-governor	Whether to request the performance CPU governor before running the mmtests workload.

Result Classes

Result class names follow mmtests sysbench conventions and encode the tested thread count, for example ‘sysbenchmutex-1’.
