The weight definitely affects movement, I always have my personal inventory to max weight to not over burden the cart. Also, and maybe this is my imagination, but it seems the weight is distributed like it is in the cart inventory screen. SO if I put ALL the silver on one side it tends to lean/pull to that side. I try and evenly distribute the weight from left to right when loading it up. I have noticed this same mechanic on boats also with leaning.

Silver is what we are trying to move too. From the base of a mountain, cross the dark forest and reach the base which is very close, less that a 10 minute walk. With the current weight it's practically impossible. After almost one hour the cart has barely moved. It cannot handle 3k and it even with 2k it's probably a time loss. That's only 3 silver veins btw, there is at least twice as much. Even the first time I used it, with significantly less weight, it kept getting stuck EVERYWHERE, again black forest.
