How do I disable Sub Asset generation for DAM assets? This feature is causing some performance degradation in CQ5/DAM and we do not use the sub assets in our application.
When some of the documents are added through DAM (For example PPT, Image, Doc, PDF) then the system automatically generates a sub asset for each page in the file. This process creates thumbnails and/or meta data for each page within a document (such as a PDF). This process can add unnecessary load to your server especially if you have documents with many pages. In an OOTB CQ5 installation these sub assets are not used for any purpose. Thus, if you are not using sub assets in your application then you may safely disable the this process.
The process below describes how to disable sub asset generation.
