LXer: Compcache: in-memory compressed swapping

Published at LXer:

The idea of memory compression—compress relatively unused pages and store them in memory itself—is simple and has been around for a long time. Compression, through the elimination of expensive disk I/O, is far faster than swapping those pages to secondary storage. When a page is needed again, it is decompressed and given back, which is, again, much faster than going to swap.
