Speed when upload a local file to S3.

Hi,

I upload a local file (1GB) to s3 with WinSCP and the command of "aws s3 cp".
As a result, WinSCP is slow than "aws s3 cp".

How to improve speed with WinSCP ?
I think that max concurrent requests is differed WinSCP and "aws s3 cp" when Multipart Upload.

The result of upload speed

WinSCP:2.3 MB/s
"aws s3 cp":8.4 Mib/s = 8.81 MB/s

Enviroment

WinSCP 5.13.6

We didn't optimize S3 transfers for speed yet. We will look at this eventually.

Thanks for a reply.

I hope to improve in the future.

Is there any roadmap/priority/schedule for fixing this issue? Just curious.
