System Memory
At time of writing, Ghost requires a system with a minimum of 1GB RAM. This is a bare minimum, and often results in the system becoming unresponsive (or requiring a reboot before performing system maintenance to free memory).
To alleviate these performance issues--without increasing the memory usage of the system itself (to keep costs of running the club low)--swap memory has been enabled.
If the amount of swap space become insufficient or needs to be configured, please follow this guide.
