12 RAMster allows RAM on other machines in a cluster to be utilized
13 dynamically and symmetrically instead of swapping to a local swap
14 disk, thus improving performance on memory-constrained workloads
15 while minimizing total RAM across the cluster. RAMster, like
16 zcache, compresses swap pages into local RAM, but then remotifies
17 the compressed pages to another node in the RAMster cluster.
