This policy controls whether the SMB server requests SMB client to use traffic compression for all SMB shares.

If you enable this policy setting, the SMB server will by default request the SMB client to compress traffic when SMB compression is enabled. See notes below.

If you disable or do not configure this policy setting, the SMB server will not by default request the SMB client to compress traffic. However traffic compression may be requested by other means. See notes below.

Note: If this policy is disabled, traffic compression may be requested by server-side per-share properties or by the SMB Client. If this is undesired, and one wishes to completely disable compression, configure the accompanying 'Disable SMB compression' policy instead.

Note: Traffic compression can only be used when both the SMB client and SMB server support and enable traffic compression.
