Pages swapped to this disk are compressed and stored in memory itself. This allows more applications to fit in given amount of memory. This is especially useful for embedded devices, OLPC and small desktops (aka virtual machines). Project home: http://code.google.com/p/compcache/ It consists of following components: - compcache.ko: Creates RAM based block device - tlsf.ko: Two Level Segregate Fit (TLSF) allocator - LZO de/compressor: (Already in mainline) Project home contains some performance numbers for TLSF and LZO. For general desktop use, this is giving *significant* performance gain under memory pressure. For now, it has been tested only on x86.
