Using Linux tc to limit the outgoing bandwidth of a web server

I use something similar and found it to balance traffic among people evenly mostly and that is sch_cake. Turns out it isn't just for home routers and works well on low traffic servers.

    tc qdisc replace dev eth0 root handle 1: cake bandwidth 4200mbit besteffort rtt 80ms nonat triple-isolate split-gso

The server is allowed 6tb/s but I don't want it to use all that. I lower to rtt to somewhere between 60ms and 80ms depending where I create the VM to optimize for the US. Default is 100ms.
