Looking at the restart in process, the only worlds that take any significant amount of time are the main world, the nether (which we think we know the cause of), and space world (I'm not entirely 100% on this one). The other worlds appear to have a negligible effect on the time it takes to restart.
In regards to the world sizes I said near the beginning of the thread, ignore them. The main world in reality only takes up about 1.83 GB, it's the backups that take up at this point nearly 132 GB.
