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. |
