 Thus, the JFFS2 in-core memory consumption is the linear
 function of the file system size.
 
+Additionally, it is worth mentioning here, that the iget() operation in JFFS2
+is the linear function of the number of nodes in the inode. The reason is
+similar to why the mount time has the linear dependency. This is why opening
+very big file or lookuping the directory with many files is very slow operation
+in JFFS2.
