Simplecom CHN411 USB C to 3 Port USB 3.0 Hub with Gigabit Ethernet ( RTL8153 ) Benchmark

This is the silver version. It is also available in black.

Below are some basic iperf benchmarks of the Simplecom CHN411 USB C to 3 Port USB 3.0 Hub with Gigabit Ethernet adapter. Only the ethernet port was benchmarked as I don’t have any very high speed USB devices to test the USB 3.0 hub ports with. The adapter is confirmed to be using a Realtek RTL8153 chip for the ethernet port. This is a very common chip and you’ll likely see the same one in use across many similar looking adapters with different branding on the outside. The testing was performed using a direct connection between the adapter and a bare metal machine that uses an Intel 82574L Gigabit NIC.

The results are on par with my expectations and I haven’t had any compatibility issues with the device across different operating systems.
