Super-server

A super-server or sometimes called a service dispatcher is a type of daemon run generally on Unix-like systems.

Principle of Super-server

Example

Usage

A super-server starts other servers when needed, normally with access to them checked by a TCP wrapper. It uses very few resources when in idle state. This can be ideal for workstations used for local web development, client/server development or low-traffic daemons with occasional usage (such as ident and SSH).

Performance

There is a slight delay in connecting to the sub-daemons. Thus, when compared to standalone servers, a super-server setup may perform worse, especially when under high load. Some servers, such as tftpd-hpa, therefore take over the internet socket and listen on it themselves for some specified interval, anticipating more connections to come.

Implementations

gollark: Well, I still prefer PotatOS superglobal mutex™ and bureacratohazardous documentation™ technology.

gollark: Ah.

gollark: &sys exec return 4

gollark: But why *spinlocks*?

gollark: Due to some config stuff, AutoBotRobot can access SPUDNET directly without going through the main osmarks.tk proxying gateway, so it has magic powers.
