Rclone copy dry-run of big S3 bucket is taking super long time to start

I've opened a support case with the Vendor, so I'll have to troubleshoot it with them.

Good idea. Let us know the outcome.

The

--s3-list-version 2

didn't improve the performance.

It was worth a try

@Martin_Sandell

Is the process of a copy to start with a compare?
I.E - Look at the destination first, then start doing GET's from the source?
Otherwise I don't understand why it would list everything from the destination bucket first (the thing that goes great)...

It should be listing both source and destination at the same time. If the destination finishes much sooner maybe you haven't noticed that?
