Fast L4 profile & MSS

Hi,

we're using Performance L4 VIP (wildcard service), with Fast L4 profile attached to it. The fast L4 profile propagates the change of the MSS value. Since the Protocol Profile (Client) is a "Client" type of profile, I wonder if there is a possibility to limit MSS to both sides, to the client, and to the server side.

This can be done on a standard type of VS... What is the impact on the box in case of changing profile type to standard? We have a large number of connections.
