I feel your pain with the lagging as my computer isn't the best but I have a large base/compound, 2 pump jacks and two quarries maxed that I circled with walls and I have 11 vending machines around my compound, that is how I make my scrap, my machines are full except for the machines that are specific to one item such as I sell cars and its has three keys in it. I have a hotel, each room has a key you buy. The other nine vending machines are items I craft and sell and they stay full. I don't build on top of other players so its not a lag issues around my base as far as I know. I don't take heli's or do cargo are any other money making activity, I build and farm scrap and sell, while I understand the need to limit vending machines that are not used and limit base size, maybe no large bases above a certain size around monuments, things like this might help the lag but doing away with vending all together or make them a item you purchase and limited base sizes severely will would seriously limit how I play and other's like me.
