SMB Compression

SMB compression allows an app, admin, or user to compress files over a network transfer. It was first introduced with Windows Server 2022 and Windows 11 Insider Preview. It will drastically reduce a network bandwidth with negligible extra compression.

Windows 11 22449.1000 build will always attempt the requested compression without testing for a better decision. Earlier SMB compressions were used to track at least 100 MB of compressed files for 500 MB of file transfer and only continue to compress the rest of the files if it was worth the efforts. Further, SMB compressions will be applied to all the requested file sizes from multiple Gigabytes to small Megabytes files.
