I don't recall from which machine the transfer was initiated but I
think the side that hogs memory is the one where the large
directory exists. So the first time you run rsync, it's just on
the source host. On subsequent runs, it's on both hosts.

IME, rsync has no problems with large files or even many files.
What it can't deal with is single directories with many files.
The algorithm used must require holding in memory some per-file
data for *all* files in the directory being synced.
If you have a news spool, a big maildir folder or some such
monstrosity, you might want to try excluding them from the sync
and see if it makes a difference.
