NAME ^

Plack::Server::Coro - Coro cooperative multithread web server

SYNOPSIS ^

  plackup --server Coro

DESCRIPTION ^

This is a Coro based Plack web server. It uses Net::Server::Coro under the hood, which means we have coroutines (threads) for each socket, active connections and a main loop.

Because it's Coro based your web application can actually block with I/O wait as long as it yields when being blocked, to the other coroutine either explicitly with cede or automatically (via Coro::* magic).

  # your web application
  use Coro::LWP;
  my $content = LWP::Simple:;get($url); # this yields to other threads when IO blocks

This server also uses Coro::AIO (and IO::AIO) if available, to send the static filehandle using sendfile(2).

The simple benchmark shows this server gives 2000 requests per second in the simple Hello World app, and 300 requests to serve 2MB photo files when used with AIO modules. Brilliantly fast.

This web server sets psgi.multithread env var on.
