Improvement in File Transfer in SharePoint 2016

SharePoint Version Mechanism Description
SharePoint 2010 Cobalt protocol Server has to fetch the whole document from the database and merge the existing content with the user changes before saving the whole document back to the content database.
SharePoint 2013 Shredded Storage This allows documents to be stored in small pieces in the content database. Because documents are already “shredded” in the database, the server does not have to fetch the whole document to merge the original contents with the changes, which reduces the server processing overhead.
SharePoint 2016 Background Intelligent Transfer Service (BITS) Improves upload and download speeds and resiliency.
