IMHO.How big is your place??
It is not about how big is the place. My 2-nodes mesh is 10m apart with line of sight usually with one door in-between at times. If distance apart, if the line of sight has obstacles e.g. cabinet, full wardrobe, walls, etc there will be significant performance hit.
I have not tested the logic, but if i have 3 nodes, I can make the signal from node 1 go straight to node 2, signal make a 90 degrees turn to node 3. It should be better than node 1 to node 3 with a lot of obstacles in-between.
