Disabling SMB signing for CIFS optimization
[ Tags:  netscaler ,   acceleration branch repeater cifs citrx layer microsoft optimization smb tips utipu wanscaler netexpert tips help ]
posted by Amos Gregory

This video TIP will demonstrate how to disable SMB signing within a CIFS environment. The Citrix WanScaler optimizes the Microsoft CIFS protocol, this protocol which was designed for a LAN environment has a very high overhead and is bandwidth intensive. CIFS deployed over a WAN environment may provide unpredictable performance and user experience. 

SMB signing digitally signs the CIFS protocol between two Micosoft servers. When SMB signing is enabled then the WanScaler cannot inspect the signed CIFS traffic. One must note, that even with SMB enabled the WanScaler will acccelerate layer 4 TCP traffic and some performance improvement will be seen. If an administrator wishes to experience the high gains of actually optimizing CIFS you must disable SMB.
