Monoceros - PSGI/Plack server with event driven connection manager, preforking workers
% plackup -s Monoceros --max-keepalive-reqs=10000 --max-workers=2 -a app.psgi
Monoceros is PSGI/Plack server supports HTTP/1.0. Monoceros has a event-driven connection manager and preforking workers. Monoceros can keep large amount of connection at minimal processes.
+--------+ +---+ worker | TCP +---------+ UNIX DOMAIN SOCKET | +--------+ --------------- | manager | ----------------------+ +---------+ | +--------+ <- keepalive -> <-- passing fds --> `---+ worker | +--------+
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/1.0 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 spawn-interval.
In addition to the options supported by plackup, Monoceros accepts following options(s). Note, the default value of several options is different from Starlet.
number of worker processes (default: 5)
seconds until timeout (default: 300)
timeout for persistent connections (default: 10)
max. number of requests allowed per single persistent connection. If set to one, persistent connections are disabled (default: 100)
max. number of requests to be handled before a worker process exits (default: 100)
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)
For more performance. I recommends you to install these module.
