Performance and measurements

In theory, the speed of a LAN connection is the TCP window size divided by the round trip time (RTT). TCP window size is generally a multiple of the maximum segment size (MTU-40, about 1460 bytes). Hey, the lower the latency on a network, the faster it will go.

Testing the throughput of the switch we plugged multiple PCs to the network drop, ran our PassMark software, and watch it fly at 1, 2.5 and 10Gigabit throughput. Any switch will show an ~5% drop in overall performance, which is transparent as far as network equipment goes. It's related to signal fault tolerances and, QoS, and the linkings. So 10GigE really never is 100% throughput.

As you can see we reach a fantastic throughput of 9500 MB/sec.

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. perfect.
