I think you are using 0.13.x, which hasn't been profiled yet.  How
fast is 0.12.6?  If you are using the quoting code, that will probably
slow things down too (rsync doesn't have to worry about that).  In
general I would expect rdiff-backup to be 3-5x slower than rsync in
terms of CPU here, since this is the worst case.

There are some old (for v0.11.1) benchmarks at
