Performance LAN

Performance and measurements

Testing the throughput of the switch we plugged multiple PCs to the network drop, ran our PassMark software, and watched it fly at 2.5 and 10 Gigabit throughput. Any switch will show a ~5% drop in overall performance, which is transparent as far as network equipment goes. It's related to signal fault tolerances and enabled QoS and linking options. So 10GigE never is 100% throughput.

As you can see we reach a fantastic throughput of ~9500 Mbps.

Above the 2.5 Gigabit throughput

And then the 10 Gigabit throughput. 

Iperf

Iperf is a widely-used network testing tool that helps in measuring the bandwidth between two hosts over a network. This command-line utility is capable of generating standard traffic streams while measuring the throughput of the network that carries it. It can test both TCP and UDP bandwidth quality on a network, providing metrics that include throughput rates, loss, and the jitter measure of the data stream's integrity. Iperf works by establishing one host as a server and another as a client. The server continuously listens for incoming connections from the client, which transmits data either for a set time or until enough data has been transferred. Iperf is especially useful because it supports various parameters that can be adjusted to customize the test according to different data sizes, bandwidths, and durations. The utility is also versatile in testing network performance across different platforms since it is available for various operating systems. 

Above a 2.5 Gigabit connection: 2.36 Gbits/sec

And then the 10 Gigabit jack: 9.43 Gbits/sec

Ping

Round-trip time (RTT) is the duration in milliseconds (ms) it takes for a network request to go from a starting point to a destination and back again to the starting runs. For the runs on either client-side, all were less than 1 ms with an average of 0ms. 

BTW we're connected to a 1 Gbps internet connection, our fibre never ever is fully utilized, so close but no sugar, though that's not switch-related.

Power consumption 

Three 10GigE-compliant PCs were connected directly to the switch. In addition, a 1G connection to the internet was built. We pushed the three PCs to 10 GigE and the WAN uplink to 800 Mbps (internet). As you can see, the power consumption is give or take 27-28 Watts. By adding full 10G links, you can only increase one or two watts per port.
