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.
