Roaming AUC files – new feature in R3

The quest for increasing performance in AX appears never-ending. With AX 2012 R3 Microsoft has added a new tool allowing us to make the AUC files global/shared.

Basic AUC file info:

AUC files are cache files made by the AX client to improve load time. Forms we have already loaded once could be loaded again from the cache without having to make a trip to the AOS for the bits and bytes. All stored in c:\users\<username>\AppData\local and then by nature user specific.

So the main challenge so far has been that user A opens the sales order form the first time, waits, caches the element and can open the form faster the second time and the same story for user B, C and all the others.

In AX 2012 R3 a new feature have been added to the client configuration with the title “Use roaming user profile to store client-side cache”. That basically says it all. We can now specify a global directory for the cache files allowing users to share the cache so when user A has opened the form user B can utilise the cache.

Still no fun for user A, but user B is in luck …
