--partial does allow the receiver to use the already transmitted data in
the delta-transfer algorithm on the next run, avoiding the need to send
it over the network again, but I guess the disk I/O of rewriting that
data to the new temporary file is the problem.  Try --partial --append;
the --append option tells rsync to make the (correct) assumption that
the destination file left by --partial matches the beginning of the
source file and just append to the existing file.
