NTP stands for Network Time Protocol and is used for clock synchronization across multiple computers. An NTP server is responsible for keeping a set of computers in sync with each other. On a local network, the server should be able to keep all client systems to within a single millisecond of each other.

Computer memory is allocated to processes as pages. Usually these pages are rather small, meaning that a process consuming a lot of memory will also be consuming a lot of pages. Searching through a multitude of pages can result in system slow downs, which is why some servers can benefit from enabling huge pages.
