Hello Dilen, sorry for rising this old post, anyway I am encountering the same problem: I have to iteratively eliminate group of faces from a mesh. Using MFnMesh.deleteFaces() is horribly slow for each face and using extractFaces doesn't work properly (faces eliminated in the last iteration re-appear in the next iteration). So how did you reconstruct the mesh using only the faces that you needed?
