TCP Window Optiimization with LFN.

Good afternoon,

My token question out to the group as I await TAC.

I have a network with Gb links between sites. Connected like such:
   Site A < 7ms > Site B < 71ms > Site C <9ms> Site D

End to end latency between Site A and Site D is 69ms. My numbers above are
the average given from CLI.

I've been reading on LFNs (Long Fat Networks) and basically I need to
optimize the TCP Window size (calculated to 8625KB).

My question, where do I implement it?
Site A and Site D? Or Site B and Site C?

If I implement on Site B and Site C, how does that impact Site C to Site D,
etc?

Any ideas?

We previously had MPLS connection with WAAS which optimized traffic. Now
since we're running Gb, we removed WAAS (our WAAS boxes were only rated to
50Mbps).

Any suggestions? Am I on the right path?

Any help is greatly appreciated.
