Starman - High-performance preforking PSGI/Plack web server
# 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).
Starman is a PSGI perl web server that has unique features such as:
- High Performance
Uses the fast XS/C HTTP header parser
Spawns workers preforked like most high performance UNIX servers do. Starman also reaps dead children and automatically restarts the worker pool.
HUPfor graceful worker restarts, and
TTOUto dynamically increase or decrease the number of worker processes, as well as
QUITto 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-appcommand 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.
Here's a simple benchmark using
-- 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.
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.
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.
