Issue

When the storage system needs to work with the contents of any directory, it must load all the directory's blocks into memory.
A large directory must occupy many buffers in the memory of the storage controller. Loading a directory involves reading blocks from the disks, which results in I/O load and processor time.
If there are many large directories in a file system, the effects noted above
might be multiplied, causing severe performance issues.
