multi port expansion hubs transfer data quickly

Is a fully plugged hub faster than an unplugged hub?

A fully plugged hub is no faster than an unplugged hub.The speed of the hub depends on its specifications and functions, not the number of plugs.Plugging in the hub just lets it connect to the device and transfer data,but it doesn't affect the speed of the data transfer itself.
