  I have got the the network setup as follows:

Branch:Users are connected to a Cisco 3750 switch with single vlan and have a single gateway router with two wan links.

            WAE appliance is connected to the same vlan with the users and the intercept/return method is WCCP gre.

Datacenter: Each of the WAN Links are connected to two separate cisco 7600 routers at the datacenter. and the servers are behind these routers.

                  The WAE appliance is connected to the two 7600s and generic gre is used for interception/return between the WAAS appliance and the

                  Cisco 7600.

After Inserting WAAS in path of the User traffic, i get all the nice compression details on the CM indicating that the WAAS workss fine but the user experience is even worse. I have also ensured that no link in the path is on Half duplex, what else could be causing a degrade of the perfrmance.

Please find attached configs template for the devices in this setup.
