We had previously seen lock contention between mounts that were either resolving paths by looking up entries in directories or writing xattrs in file inodes as they did archiving work. The previous attempt to avoid this contention was to give each directory its own inode number allocator which ensured that inodes created for entries in the directory wouldn't share lock groups with inodes in other directories. But this creates the problem of operating on few files per lock for reasonably small directories. It also creates more server commits as each new directory gets its inode allocation reservation. The fix is to have mount-wide seperate allocators for directories and for everything else. This puts directories and files in seperate groups and locks, regardless of directory population.
