This can be a little frustrating when you're trying to upload alot of files to S3, i.e. updating a static site.

This is more of an implementation issue where the current approach (while clever), tries to flatten all the upload requests and uploads them one at a time.

The better approach would be to use a TransferManager and batch upload all the Entries together.

I want to take this on – but there's some code I'd like to refactor to get there.
