As the manual said this tunable "/proc/fs/lustre/llite/<fsname>-<uid>/max_cache_mb" is the maximum amount of inactive data cached by the client.  I think it's  active data not inactive that is frequently accessed. And with this client reads data from cache without disk access.
Could someone give some explaination about the tunable and suggestions on how to adjust this parameter to get high performance?

We really appreciate your any ideas.
