Appfabric CU for SP2013

[journeym]

Is there a reason to use CU5 for AppFabric exclusively for SP2013?
It works way better performance wise with CU7 + backgroundGC patch (http://www.jeremytaylor.net/2015/09/17/how-to-patch-sharepoint-distributed-cache-the-proper-way/)

You're of course free to patch whatever AppFabric CU version you want after the install is complete, but as far as the official version that the PrerequisiteInstaller.exe installs and expects I believe that's still CU5 so we'll stick with that for now.

Having said that, the function Install-AppFabricCU will try to install CU7 first (after SP is originally installed) if the expected installation binary is found. Then CU6, then CU5 etc.
