Network Performance Testing
We used two systems in our testing today. ASRock shipped us a Z390 Phantom Gaming SLI/ac for the 2.5GbE test. We wanted to take the test all the way out to 10GbE, so we tapped our enterprise SSD test system with an ASRock X299 Pro Gaming i9 XE system for the rest of the tests.
In the middle between the test system and the enterprise server, we used a Netgear ProSafe M4200 with support for 1GbE, 2.5GbE, 5GbE, and 10GbE speeds. The M4200 is just one of many Netgear switches with support for multi-gigabit speeds available today.
Network and telecom engineers use bits per second, and this is the test results in that format for maximum throughput. We used Ixia's ixChariot software to record the data. Network traffic carries an overhead, so 10-Gigabit Ethernet (GbE) is actually closer to 9.5GbE.
Iometer has a little-known network test that we used to measure performance in megabytes per second, what most of our reader's user to determine network and storage performance. This charge gives most readers a better understanding of the maximum one-way throughput.
Timed Data Transfer
We used 70-second test runs in the tests today. This chart shows the amount of data transferred over each 70-second run with each connection speed.
The last test shows the response time for each connection technology. If you use storage over a network, the response time adds to the storage's response time. If you invest in low-latency flash (SSDs), it's best to use a high-performance network to get the most out of the system. The increased latency is why iSCSI and SMB performance on a NAS is slower than a local disk even when using the same media. With each step up the network speed ladder, the latency drops significantly.
