Many are using it on large scales. There are scaling issues
and mitigation depends on the definition of large.

Is that a single file nearly 600GB or multiple files?
Rsync's memory footprint is dependant on two things: the
file list and the number of checksum blocks of the largest
2.5.6 and earlier releases also have a performance issue
with large files.
