    Description

      This is a mirror issue of LU-11509:LDLM: replace client lock LRU with improved cache algorithm. The current client side page LRU cache algorithm may evict frequently used pages when performing operations like `ls` or `find` on large directories, specifically during ll_iterate. An improved cache replacement algorithm (e.g ARC) might be helpful to ensure more frequently accessed pages remain resident on the client, preventing unnecessary eviction.

      paf0186, adilger, given your expertise, could you please provide your insight on the feasibility and potential benefits of this approach?
