large_​file_​optimization_​advanced


The Large File Optimization feature improves performance and reliability when delivering large files. You need this behavior for objects larger than 1.​8GB, and it's recommended for anything over 100MB. You should apply it only to the specific content to be optimized, such as a download directory's .gz files. Note that it is best to use Net​Storage for objects larger than 1.​8GB.

This advanced behavior provides additional HTTP/2 options not present in the large​_file​_optimization behavior.
