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.
