The `groups_map` array (which indicates the group an element belongs to) is only intended to reduce loops when creating groups, speeding up that part of the code. But on the downside, it requires more memory usage, and adds one more step to access groups (`groups_offs[groups_map[i]]` instead of just `groups_offs[i]`). So removing that array decreases memory usage and speeds up access in another part of the code. The profile showed a +6% advantage when the Weld modifier affects large portions of the mesh. But it also showed a loss of around -0.6% in performance for cases where the Weld modifier affects small parts of the mesh. The biggest benefit is to save memory and speed up some cases. |
