micromm/munmap
Micro-benchmark measuring munmap latency for anonymous mappings.
Benchmark Profile
Type: Micro
Kernel subsystem: Memory management, VMA handling
Coverage: Directly measured
Topology: Single role: executer
Overview
Measures the cost of unmapping anonymous memory regions. Sensitive to changes in the kernel mm subsystem, particularly vma management and mmap_lock contention.
