Each rsync backup has two processes on the backup server, but only one will be doing compression. So, yes, compression for a single backup is single-threaded (as rsync is).
However, the backup server usually runs multiple backups (configurable), and, in the steady state, the amount of compression required isn't very large: only new files not already in the pool need to be compressed. It's not likely compression is a bottleneck.
