The delta-transfer algorithm should limit the network traffic between the sending and receiving rsyncs, so I'm assuming your complaint is about disk I/O. By default, the receiving side reads the entire old destination file to determine what blocks have changed and then rewrites the entire destination file. --inplace will reduce the write to the changed blocks only, provided that the delta-transfer algorithm is enabled. If you know that your files change only by appending, you can tell rsync that with the --append option and it will just copy the appended data.
