I have a customer that has been experiencing latency on an application that they have been running that launches from a CIFS file share at the home office over a 40msec WAN connection. From packet captures, we can see that the WAE is in fact optimizing the file read/writes for the files the application is calling but it still is sending the Query_Path_Info, etc calls to the origin server as would be expected for file coherency.
The question here revolves around DFS. The customer would like to place a DFS server in the remote office and run the application from the DFS server share. Will this help at all by mitigating the need to send the query packets across the WAN?
