Microsoft has released Windows 11 Build 22449 to the Dev channel, and it brings the usual slew of tweaks and changes. One that stands out is a change to the SMB compression behavior that’ll speed up local network file transfers.
There are many small changes and bug fixes introduced with this update (and probably some new bugs that’ll be introduced), but what causes our attention is the Server Message Block (SMB) compression behavior change. Microsoft first introduced SMB compression with Windows 11. Basically, it’s designed to speed up file transfers over a local network.
