At least with respect to macOS, the Realtek 8153 chipsets in these docks suffer from having to use the built-in ECM driver. If you're on Apple Silicon, that's your only option. If you're on Intel, there are some flaky but more performant drivers from Realtek available. The ECM driver will cause high CPU load and for many users, will result in performance that's worse than wifi because of it. You'll also get audio dropouts and system hitches from the CPU loading.

If you can find an adapter that uses the Realtek 8156 chipset, which I believe the CalDigit TS4 uses, macOS will utilize the NCM driver and your performance will be rock solid.

ECM is a very primitive USB protocol for ethernet, whereas NCM is a more modern and performant one. NCM is to ECM as UASP is to BOT mode, if you're familiar with USB external drives.
