Zcache doubles RAM efficiency while providing a significant
performance boosts on many workloads. Zcache uses
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. Zcache2
is a complete rewrite of the older zcache; it was intended to
be a merge but that has been blocked due to political and
technical disagreements. It is intended that they will merge
again in the future. Until then, zcache2 is a single-node
version of ramster.
