Subsystem Testing Continued….
LAN Speed Test software was used with the Windows Task Manager to determine the performance levels of the onboard network interface. LAN Speed Test was used to measure bandwidth and transfer speeds, while Windows Task Manager monitored CPU utilization on the test system. For the testing, an 800MB file test was used with the default packet configuration for the application. The test was run three times with the middle result chosen. Results were captured for the low, medium, and high transfer rates. The test was performed using a plenum rated category 5e crossover cable to bypass any traffic, routing, or other transfer issues and possible packet loss or corruption that can be caused by a router/switch or hub. The cables were connected between two test machines, one using the onboard NIC(s) of the board being reviewed and the other is an Intel X540 Converged Network adapter. It supports 10/100/1000/10000Mbps speeds.
Wireless network testing, if applicable was performed using a connection to an 802.11/AC enabled wireless router and then sent to a test machine connected to the same router via a RJ-45 LAN connection. The target system network adapter is an i219v PCI-Express Gigabit Ethernet controller integrated into an ASUS Maximus XI Formula motherboard. The network settings for both network controllers and the router are all at their defaults and the 802.11/AC router has no other devices connected to it.
For its wired networking, the ASUS PRIME X570 Pro has an integrated Intel i211-AT network controller supporting 10/100/1000Mbps speeds.
The Intel i211-AT controller averaged 89.11MB/s in the write test and 97.31MB/s in the read test. The maximum transfer rates were 90.28MB/s in the write test and 104.53MB/s in the read or download test. The minimum transfer rates were 88.16MB/s in the write test and 61.36MB/s in the read test.
CPU utilization in the write test hung around 2%. There were some spikes here and there but overall it was level for most of the test. The CPU usage in the read test was also 2%. However, the usage was more consistent here.
