What is Magento Compilation?

The Magento Compilation is a feature that allows you to compile all Magento installation files (source code, including plugins) into a single folder in order to create a single include path. This feature is designed to improve the performance of your online store and is supposed to give between 25% and 50% increase in your page load speed.

If compilation is turned on in Magento, whenever there’s a change of source in the root folder, you need to re-run the compilation process for that change to be applied on your website.

“Please re-run Magento compile command” message

please re-run magento compile command

This is a system message that appears whenever there’s a change in Magento source. Every time the upgrade command is finished, you’ll see this message.

To run the compile command, type this line:

php bin/magento setup:di:compile

In Magento 2, if you already disable compilation or are working in dev-mode, you can ignore this message.
