There is a similar enhancement request:

This would take a major redesign of rsync which I don't think is going
to happen anytime soon.  It may make more sense to write a new, better
designed tool (possibly adopting some of Wayne and Martin Pool's ideas
for "superlifter") that is capable of parallelism.  I would be
interested in helping if I could find the time.
