         A compressed cache for file pages.

         It takes active file pages that are in the process of being reclaimed

         and attempts to compress them into a dynamically allocated RAM-based

         memory pool.

         If this process is successful, when those file pages needed again, the

         I/O reading operation was avoided. This results in a significant performance

         gains under memory pressure for systems full with file pages.
