Sugar Developer Guide Version 5.1

File Caching

Much of the user interface is built dynamically via templates from metadata and language string files. SugarCRM implements a file caching mechanism to improve the performance of the system by reducing the number of static metadata and language files that need to be resolved at runtime. This directory stores the cached template and language string files.

When developing in SugarCRM, we suggest that you turn on Developer Mode (Admin->System Settings->Advanced->Developer Mode) which causes the system to ignore these cached files. This is especially helpful when you are altering templates, metadata or language files directly. When using Module Builder or Studio, the system will automatically refresh the file cache. Be sure to turn Developer Mode off when you have completed your customizations as Developer Mode does degrade system performance.
