Have any of you already requested the hotfix for SMB and how does it work for you ?

The "hotfix" in this case is really a new firmware image for the appliance.
I imagine it's similar to the fix for non-SMB appliances.

We read: SMB (600/700/900/1100/1200R/1400) - Contact Check Point Support to get a Hotfix for this issue. A Support Engineer will make sure the Hotfix is compatible with your environment before providing the Hotfix.

Or disable the TCP SACK feature system wise.
