| Zcache doubles RAM efficiency while providing a significant | |
| performance boosts on many workloads. Zcache uses lzo1x | |
| compression and an in-kernel implementation of transcendent | |
| memory to store clean page cache pages and swap in RAM, | |
| providing a noticeable reduction in disk I/O. |
