This advanced option must be set in startup .ini files
To switch off the functionality of loading custom properties from the extension folder ..common\extensions\custom\properties\ , set the advanced option XS_ENABLE_FAST_CUSTOM_PROPERTY_LOADING to FALSE in a startup .ini file using the following command:
When you do this, the custom properties are loaded from all folders and subfolders in ..common\extensions , and from the locations defined in XS_EXTENSION_DIRECTORY. This may cause performance issues and loading failures when custom properties are used.
Loading custom properties from ..common\extensions\custom\properties\ speeds up the loading process and solves loading problems caused by other software components in other extension folders.
