BIG IP send Zero-Window to Server

i've found the BIG-IP LTM 3600 send Zero-Window to Server frequently which caused tcp delay.

 

VS configuration standard have SSL profile TCP porfile client tcp profile server use client profile

 

I've already use tcp-lan-optimistic profile for server , but it not works.

    The bigip will only send Zero-Window to server side if it got Zero-window from client, or if the client-side window is full, which is a signal that the client-side is too slow compared to the server-side. Without a review of the traffic captures, it will be difficult to suggest what the best option is (apart from use a profile on client side that is optimized for WAN -- it has bigger buffers)
