Bit unrelated question and please excuse me if it's going in a wrong way - any plans to have sort of multithread support in rsync? Being single thread limited is painfully slow. I'm concerned on data reads ( disks do much better being read in parallel ) and checksumming - doing 2nd pass of rsync over medium sized mysql db of around 2tb is literally slower than just something like tar ..|zstd | ssh "zstd -| tar -".

Doing copy with rclone can be much much faster as well.
