S3 Compatible slow uploading when s3-signatureversion only 4 #4845
looks like the GitHub version of this, opened two days later. Above reference will create a link back to here.
So should the GitHub issue be closed? Note that there is still an open question on signature version usage.
The issue detailed aws cli speed further. One possible reason it goes faster is due to multiple connections.
How do I use the AWS CLI to perform a multipart upload of a file to Amazon S3?
I’m pretty sure Duplicati uploads a single file over one connection, whereas aws s3 cp might be using ten.
Duplicati can do different files concurrently over different connections. Unfortunately you found it didn’t help.
