  Yes, rsync uses large amounts of memory when the fileset is large.
Plus, depending on your CPU, you might want to avoid using ssh encryption
too.

  Usually if it is a LAN to LAN copy, cpdup over NFS will be WAY faster
than rsync, and use little memory.  I've used cpdup for moving mail to a
new server.  I synced before the cutover, shutdown the mail server, synced
one more, and then brought up the mail server on the system.  Very tidy.
