Starwoman - because Starman does the same thing over and over again expecting different results
# Run app.psgi with the default settings > starwoman # run with Server::Starter > start_server --port 127.0.0.1:80 -- starwoman --workers 32 myapp.psgi # UNIX domain sockets > starwoman --listen /tmp/starwoman.sock
Read more options and configurations by running `perldoc starwoman` (lower-case s).
Starwoman 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. Starwoman 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 Starwoman 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: Starwoman (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.
Because Starwoman runs as a preforking model, it is not recommended to serve the requests directly from the internet, especially when slow requesting clients are taken into consideration. It is suggested to put Starwoman workers behind the frontend servers such as nginx, and use HTTP proxy with TCP or UNIX sockets.
This is a fork of Starman for one particular reason: to stop the endless forking of immediately dying children when app.psgi can't be loaded, which flooded the log file and pegged the CPU. Starman hasn't been maintained, hence the fork. Do not assume I will be any better about maintaining this, considering how much attention I give to projects I wrote myself.
