Active-State Power Management
Active-State Power Management (ASPM) saves power in the PCIe subsystem by setting a lower power state for PCIe links when the devices to which they connect are not in use. When ASPM is enabled, device latency increases because of the time required to transition the link between different power states. Therefore, ASPM support is disabled here for performance benchmarking.
