I am using AWS SDK for java. Is there any difference in performance when passing InputStream instead of File in uploading to AWS S3 using TransferManager multipart upload? Should one be preferred over the other or is it just a matter of choice?

Update: In my tests, I found that using an input stream was always slower than using a file. [File Size is 512MB]

P.S. I am using Spring so what I get is a MultipartFile the contents of which I store in the temp file just for uploading to S3.

Faiz you can yuse Amplify SDK for S3 file upload. It's really fast for upload and download files instead of TransferManagerUtils.
