Abstract
Techniques are described for compressing cache pages from an LRU (Least-Recently-Used) queue so that data takes longer to age off and be removed from the cache. This increases the likelihood that data will be available within the cache upon subsequent re-access, reducing the need for costly disk accesses due to cache misses.
