Perl::Critic::Policy::Community::Threads3pm

Overview

Perl interpreter threads are officially discouraged. They were created to emulate fork() in Windows environments, and are not fast or lightweight as one may expect. Non-blocking code or I/O can be easily parallelized by using an event loop such as POE, IO::Async, or Mojo::IOLoop. Blocking code is usually better parallelized by forking, which on Unix-like systems is fast and efficient. Modules such as forks and Parallel::Prefork can make forking easier to work with, as well as forking modules for event loops such as POE::Wheel::Run, IO::Async::Process, or "subprocess" in Mojo::IOLoop.
