Split n-gons
Another problem is that the algorithm produces n-gons, which sometimes leads to bad results, and may not work if you intend to export the character to some other application. This can be fixed by the Split n-gons button.

After triangulating n-gons the character weighs
Verts: 8323, Edges: 20051, Faces: 11770
The number of edges and faces has gone up considerably, but I'm not sure that this affects performance, since complicated n-gons have been replaced by simple triangles. The number of vertices stays the same, which is what I think is most important for performance.
