Sockets VS Collision boxes for Player Building Snapping Points.

Hi I am making a game in which the players can build houses piece by piece, the snapping points are defined by collision boxes attached to each structure piece. The collision boxes only overlap 1 unique object type. Each structure has roughly 5 or more collision boxes for snapping.

My thoughts is that when 100’s of these are spawned in by the player, there are going to be a lot of collision boxes in that area.

Would it impact performance at a certain point, and would snapping through sockets be more performance friendly?
