It can, depending on the use case:
 -- It can remove a lot of uneccessary temporary creation.
 -- IIUC, it works on blocks of data at a time, and thus can keep
things in cache more when working with large data sets.
  -- It can (optionally) use multiple threads for easy parallelization.

All you can do is try it on your use-case and see what you get. It's a
pretty light lift to try.
