micromm/vmalloc

Micro-benchmark measuring vmalloc/vfree latency.

Benchmark Profile

• Type: Micro

• Kernel subsystem: Memory management, vmalloc allocator

• Coverage: Directly measured

• Topology: Single role: executer

Overview

Measures the round-trip cost of vmalloc() and vfree() in the kernel. Sensitive to changes in the vmalloc allocator, cache pressure, and TLB/page-table management.

Result Classes

Result class names describe the operation and unit.
