2 bool "Dynamic compression of swap pages and clean pagecache pages"
3 # X86 dependency is because zsmalloc uses non-portable pte/tlb
5 depends on (CLEANCACHE || FRONTSWAP) && CRYPTO && X86
10 Zcache doubles RAM efficiency while providing a significant
11 performance boosts on many workloads. Zcache uses
12 compression and an in-kernel implementation of transcendent
13 memory to store clean page cache pages and swap in RAM,
14 providing a noticeable reduction in disk I/O.
