```
Set `bandwidth_limit` in each proxy's configure to enable this feature. Supported units are `MB` and `KB`.
Set `bandwidth_limit_mode` to `client` or `server` to limit bandwidth on the client or server side. Default is `client`.
### TCP Stream Multiplexing
frp supports tcp stream multiplexing since v0.10.0 like HTTP2 Multiplexing, in which case all logic connections to the same frpc are multiplexed into the same TCP connection.
