Both aggregate_stat (IT_5) and readdir+ are candidate for that, maybe need to be combined together.</p> LU-23

Improve performance for traversing large directory with readdir+

This can be driven by the client to request attributes for specific FIDs, in a variety of access patterns (e.g. depth-first or breadth-first directory traversal), rather than only sequential readdir.</p> Related LU-14139 LU-14380 LU-31 Bugzilla ID 17845.0 Development Rank 1|hzw2nr: Rank (Obsolete) 10513
