mmtests/kernbench
Kernel compile benchmark measuring build throughput across CPU counts.
Benchmark Profile
Type: Macro
Kernel subsystem: Scheduler, memory management, filesystem I/O
Coverage: Inferred from kernel build throughput
Topology: Single role: executer
Overview
kernbench compiles the Linux kernel at multiple parallelism levels to measure build throughput and scalability. It stresses the CPU, memory system, and file I/O subsystems simultaneously.
