mmtests/stressng-vm-splice

stress-ng vm-splice stressor measuring zero-copy splice throughput.

Benchmark Profile

• Type: Micro

• Kernel subsystem: Pipes, zero-copy I/O, memory management

• Coverage: Directly measured

• Topology: Single role: executer

Overview

Measures zero-copy data transfer performance using vm_splice. Sensitive to changes in pipe and zero-copy I/O paths in the kernel.
