What's the best way to limit connection speed for each vless client? 限制每个 vless 客户端连接速度的最佳方法是什么？

My xray configuration has just a single vless inbound (with xtls-rprx-vision flow) and 5 clients. I would like to limit the available bandwidth for each client, for example 500 kB/s download and 250 kB/s upload so that everyone could always get a fair share at any moment. Does Xray-core have a native solution for limiting bandwidth? I checked the english documentation and found nothing on this matter. What server-side tools could I use to limit the connection speed of Xray users? All clients are connecting from the same CGNAT subnet and there's a small chance they might have the same IP.
