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.

       Kazuho Oku wrote Net::Server::SS::PreFork that makes it easy to add Server::Starter support to this software.
