There's a bug I see (and I created) in current upstream master, where --no-check-md5 will still do the file I/O on local files to get the md5sums for them, exactly to decide if it can do remote copying.  That's annoying.

This bug also means --no-check-md5 won't, as you might expect, disable remote copying.  As no one has asked to be able to disable remote copying, I never coded for it.

I'll think about this a bit.  There's probably a cleaner way to solve both problems.

While this feature is fantastic, I can't find a lot of detail on it in general. I wonder how to disable it?

During initial uploads at least, our DirectConnect link seems to be faster in copying the files themselves than s3cmd is at telling S3 to "remote copy" objects.

Would that simply be using s3cmd switch  --no-check-md5 ?

This would seem likely to reduce the RAM required to enumerate the source files too?

Thanks,
Mike
