DFS/FRS Performance Tuning

Does any have resources on performance tuning DFS and FRS?  

FRS is set up hub and spoke.  1 AD DFS Root with 5 shares approx.  40GB of data.
5 core shares in the root.  only 2 must have nearly instantaneous replication.

the two shares of concern have 0 cache time and replication priority is set high with overide schedule checked.  Any suggestions?

Read this wasn't much help but thanks anyway
If the "spokes" are in different sites in AD you can set the replication intervals shorter.
Other than that I don't think there is much.
Though you should read through these pages to gain more of an understanding of FRS/DFS:

Also, search through the KB regularly as MS likes to update info/specs and not update the new info in  all the places it should.
I learned that the hard way..........
