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