+Background Workers
+==================
+
+**This feature is experimental**.
+
+Depending on your configuration, some features can slow down the application if they are executed in the same process as the HTTP request.
+Kanboard can delegate these tasks to a background worker that listen for incoming events.
+
+Example of feature that may slow down Kanboard:
+
+- Sending emails via an external SMTP server can take several seconds
+- Sending notifications to external services
+
+This feature is optional and require the installation of a queue daemon on your server.
+
+### Beanstalk

+
+- To install Beanstalk, you can simply use the package manager of your Linux distribution
+- Install the [Kanboard plugin for Beanstalk](https://kanboard.net/plugin/beanstalk)
+- Start the worker with the Kanboard command line tool: `./kanboard worker`
+
+### RabbitMQ
+
+[RabbitMQ](https://www.rabbitmq.com/) is a robust messaging system that is more suitable for high-availability infrastructure.
