Twiggy is a lightweight and fast HTTP server with unique features: * Can run any PSGI applications. Fully supports psgi.nonblocking and psgi.streaming interfaces. * This server uses AnyEvent and runs in a non-blocking event loop, so it's best to run event-driven web applications that runs I/O bound jobs or delayed responses such as long-poll, WebSocket or streaming content (server push). * Uses XS/C based HTTP header parser for the best performance. (optional) * The memory required to run twiggy is 6MB and it can serve more than 4500 req/s with a single process on Perl 5.10 with MacBook Pro 13" late 2009. * Supports Server::Starter for hot deploy and graceful restarts.
