Magento Community Edition, 1.9.x

Compilation

The compilation process can improve the performance of a Magento 1.x installation by combining separate include files from various modules into a single file. Before compiling an installation, the following file on the server must be writable:

 /var/www/html/magento1/latest_ce/includes/config.php

The compiler is disabled by default. The first time you run the compiler, the status changes to “Enabled.” A summary of the compilation state appears at the top, and includes the status of the compiler and state of the compilation, the number of files compiled, and the scope of the compilation. To make changes to a compiled installation, you must first disable the compiler. Then after making the necessary changes, enable the compiler, and run the compiler again.

To run the compiler:

1. On the Admin menu, select System > Tools > Compilation.
2. Click the Run Compilation Process button.

To disable the compiler:

Click the Disable button.
