mmtests/stressng-class-io-parallel
stress-ng parallel I/O workload measuring throughput across multiple I/O stressors.
Benchmark Profile
Type: Micro
Kernel subsystem: Filesystem, block I/O, page cache
Coverage: Directly measured
Topology: Single role: executer
Overview
Runs the stress-ng class-io-parallel workload through mmtests, combining multiple I/O-oriented stressors in parallel. Sensitive to block I/O, filesystem, page-cache, and asynchronous I/O path changes.
