Server Architecture

Software Software

nginx

Nginx supports both the single-process event-driven architecture and the multiple-process event-driven architecture.

lighttpd

Lighttpd uses the single-process event-driven architecture.

squid

Squid uses the single-process event-driven architecture, because the main process of squid handles all kind of network connections, despite that different processes can handle disk I/O under the diskd configuration.

Varnish

Varnish uses the single-process event-driven architecture, because the main process of Varnish uses poll to process events.
