#max_put_chunk_size ⇒ Integer (readonly)

Amazon S3 limits max chunk size that can be uploaded/copied in a single request to 5GB. Other S3-compatible storages (like, Ceph) do not have such limit. Ceph shows much better performance when file is copied as a whole, in a single request. fog-aws user can use these settings to configure chunk sizes. A non-positive value will tell fog-aws to use a single put/copy request regardless of file size.

Returns:
