Got it. Is there some flag I can set to tell rclone to not wait for acknowledgements? As long as the file is probably uploaded, I don't care about the acknowledgement.
I ctrl-F for "acknowledge" in the global flags and found nothing relevant. I also ctrl-F's for --timeout and found a few things that might be relevant, just not sure what the precise flag to use is.
I'll also tag on that even when I use use --s3-disable-checksum, using the -vvvvvv flag, I still see the MD5 hashes of the files. Am I not using the correct flag to disable checksums?
