Yes, possibly it's because it retrieves the MObjects and MDagPaths from the strings that cmds.ls() actually returns. Then it will have to query it's database to attach the respective function sets to the object ( and possibly more ). This makes each API wrapped object quite an expensive little fella ;).
Once more this shows that you either get speed at the expense of convenience for the programmer or you sacrifice it.
