My upload speed is slow, best slider setting?

[Mikzxr]

My internet has great download (115mbps) but slow upload speed (5mbps). If I leave the download slider at 70 and the upload slider at 70, DSL gives me a B grade. If I lower the slider, the grade gets worse (tried 40 and 50%). If I move the slider to 85, I get an A. Does this seem backwards to anyone or do I not understand the sliders?

Well the sliders effectively reduce the speed so that's probably why the rating goes down, but the idea is to balance usage between devices on the network.

Anyway if your upload bandwidth is often being used up, it might be more important to use anti-bufferbloat on that rather than the download, because your download bandwidth is pretty good.
