Take a moment to properly read the manpage, the above indicates you've
never gone beyond the option summary.
Further on, the options are discussed in detail:
With this option rsync’s delta-transfer algorithm is not used
and the whole file is sent as-is instead. The transfer may be
faster if this option is used when the bandwidth between the
source and destination machines is higher than the bandwidth to
disk (especially when the "disk" is actually a networked
filesystem). This is the default when both the source and des‐
tination are specified as local paths, but only if no batch-
writing option is in effect.
