Hi Andreas,
Yes, this afmRefreshAsync feature is still effective in this setup if this is enabled on 5.0.3.X based AFM cache cluster.

Hi,
Due to having a data analysis software that isn't running well at all in our AFM caches, it runs 4-6 times slower on an AFM cache than on a non-AFM fileset on the same storage system, I wanted to try out the afmRefreshAsync feature that came with 5.0.3 to see if it is the cache data refresh that is holding things up.
Enabling this feature has had zero impact on performance of the software though.
The storage cluster is running 5.0.3.x, and afmRefreshAsync has been set there, but at the moment the remote-mounting client cluster is still running 5.0.2.x.
Would this feature still have any effect in this setup?
Regards,
Andreas Mattsson
