But in some cases, LRU algorithm causes many page faults, so improving LRU page replacement algorithm can reduce page faults, and therefore improve the performance of the system.

On basis of LRU algorithm,this paper proposes an improved replacement algorithm for cooperative Web cache,which uses different storage strategies aiming at different sizes of documents.

LRU algorithm needs the hardware support when applied to manage the memory of the computer,therefore its application is limited to a certian extent.
