Bisync causes high CPU if `--ignore-checksum` is not passed, even with no diff

Thanks @ncw for your quick response!

Too bad that --ignore-checksum combines ignoring checksum both for (1) finding changes and (2) verifying that copied files were copied successfully...

I'll try to use the hasher backend and see its performance but I also came up with another idea:

  • Keep running (as a cronjob) rclone bisync every 15 minutes with --ignore-checksum.
  • Running (as an extra crobjob) rclone check once a day to verify all checksums.

What do you think? Does it sound like a reasonable plan?

Thanks again!!
