DESCRIPTION

Monoceros is PSGI/Plack server supports HTTP/1.1. Monoceros has a event-driven connection manager and preforking workers. Monoceros can keep large amount of connection at minimal processes.

Features of Monoceros

- a manager process based on AnyEvent keeps over C10K connections

- uses IO::FDPass for passing a file descriptor to workers

- supports HTTP/1.1 and also supports HTTP/1.0 keepalive

And this server inherit Starlet. Monoceros supports following features too.

- prefork and graceful shutdown using Parallel::Prefork

- hot deploy using Server::Starter

- fast HTTP processing using HTTP::Parser::XS (optional)

But Monoceros does not support max-keepalive-reqs and spawn-interval.

COMMAND LINE OPTIONS

In addition to the options supported by plackup, Monoceros accepts following options(s). Note, the default value of several options is different from Starlet.

--max-workers=#

number of worker processes (default: 5)

--timeout=#

seconds until timeout (default: 300)

--keepalive-timeout=#

timeout for persistent connections (default: 10)

--max-reqs-per-child=#

max. number of requests to be handled before a worker process exits (default: 100)

--min-reqs-per-child=#

if set, randomizes the number of requests handled by a single worker process between the value and that supplied by --max-reqs-per-chlid (default: none)

RECOMMENDED MODULES

For more performance. I recommends you to install these module.
