NAME Starman - High-performance preforking PSGI/Plack web server SYNOPSIS # Run app.psgi with the default settings > starman # run with Server::Starter > start_server --port 127.0.0.1:80 -- starman --workers 32 myapp.psgi # UNIX domain sockets > starman --listen /tmp/starman.sock DESCRIPTION Starman is a PSGI perl web server that has unique features such as: High Performance Uses the fast XS/C HTTP header parser Preforking Spawns workers preforked like most high performance UNIX servers do. Starman also reaps dead children and automatically restarts the worker pool. Signals Supports "HUP" for graceful worker restarts, and "TTIN"/"TTOU" to dynamically increase or decrease the number of worker processes, as well as "QUIT" to gracefully shutdown the worker processes. Superdaemon aware Supports Server::Starter for hot deploy and graceful restarts. Multiple interfaces and UNIX Domain Socket support Able to listen on multiple intefaces including UNIX sockets. Small memory footprint Preloading the applications with "--preload-app" command line option enables copy-on-write friendly memory management. Also, the minimum memory usage Starman requires for the master process is 7MB and children (workers) is less than 3.0MB. PSGI compatible Can run any PSGI applications and frameworks HTTP/1.1 support Supports chunked requests and responses, keep-alive and pipeline requests. UNIX only This server does not support Win32. PERFORMANCE Here's a simple benchmark using "Hello.psgi". -- server: Starman (workers=10) Requests per second: 6849.16 [#/sec] (mean) -- server: Twiggy Requests per second: 3911.78 [#/sec] (mean) -- server: AnyEvent::HTTPD Requests per second: 2738.49 [#/sec] (mean) -- server: HTTP::Server::PSGI Requests per second: 2218.16 [#/sec] (mean) -- server: HTTP::Server::PSGI (workers=10) Requests per second: 2792.99 [#/sec] (mean) -- server: HTTP::Server::Simple Requests per second: 1435.50 [#/sec] (mean) -- server: Corona Requests per second: 2332.00 [#/sec] (mean) -- server: POE Requests per second: 503.59 [#/sec] (mean) This benchmark was processed with "ab -c 10 -t 1 -k" on MacBook Pro 13" late 2009 model on Mac OS X 10.6.2 with perl 5.10.0. YMMV. NAMING Starman? The name Starman is taken from the song (*Star na Otoko*) by the Japanese rock band Unicorn (yes, Unicorn!). It's also known as a song by David Bowie, a power-up from Super Mario Brothers and a character from Earthbound, all of which I love. Why the cute name instead of more descriptive namespace? Are you on drugs? I'm sick of naming Perl software like HTTP::Server::PSGI::How::Its::Written::With::What::Module and people call it HSPHIWWWM on IRC. It's hard to say on speeches and newbies would ask questions what they stand for every day. That's crazy. This module actually includes the longer alias and an empty subclass HTTP::Server::PSGI::Net::Server::PreFork for those who like to type more ::'s. It would actually help you find this software by searching for *PSGI Server Prefork* on CPAN, which i believe is a good thing. Yes, maybe I'm on drugs. We'll see. AUTHOR Tatsuhiko Miyagawa <firstname.lastname@example.org> Andy Grundman wrote Catalyst::Engine::HTTP::Prefork, which this module is heavily based on. Kazuho Oku wrote Net::Server::SS::PreFork that makes it easy to add Server::Starter support to this software.
