Winbox 3rc has access to the two flows to bandwidth control.
The upload is still tricky, requiring more than the necessary amount to make it work.
It also requires more in the burst amount window.
If I don’t change that from 100k it doesn’t ever get above 80Mbps it seems.
Changing it to 1M and the amount to about 150M seems to let it get to 100Mbps in real throughput on a speed test.
Not exactly working, but tweaking it got it where I needed it to be for now anyways.
