Hi, my first post. I'm just wondering if on CBQ does root queue = qInternet + child queue?

However when I try HFSC, root queue = qInternet, which I think is correct representation, yes?

Anyway, I have to almost times 2 of my actual internet bandwidth for cbq to work to saturate my bandwidth. If I put  below my internet speed, it seems to halve it every time and never saturate
