Another QoS Limter Question - RB4011GS

So I have a RB4011GS in factory default settings other than the password.

I’m a tech guy, work as cloud engineer, but for the life of me can’t figure out to get a 10Mbit/10Mbit QOS/Limiter working.

ETH1 is WAN, Fios gigE
ETH2 is Macbook Pro, where I’m doing all of my testing.

I’ve tried disabling FastTrack/Fastpath, but I know it’s skipping the limiter somehow…

Some background: I’m running a BUNCH of Flent tests, trying to limit my… upload as out of the box they seem to favor upload over download.
I mean, I can get line speed down from a test Flent server when only downloading.

When running in bi-directional mode - I get line speed up, but ~400-600mbit down.

Trying to set a upload/download limiter for 900/900Mbit to keep them sweet sweet ping times and general responsiveness.

PS: Thanks in advance, I know this is covered like 100’s of times on the internet.

Was this not the right place to ask/post for help?

I understand the frustration if this is the case.
