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

       Read more options and configurations by running `perldoc starman` (lower-case s).

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 interfaces 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.
