Large File Optimization Advanced

This behavior can only be configured for you by ​Akamai​ Professional Services and isn't directly accessible in the ​Control Center​'s Property Manager application. You can review the behavior options and work with your account representative to have them implemented.

The Large File Optimization feature improves performance and reliability when delivering large files. This behavior is required for objects larger than 1.8GB, and 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. It is best to use NetStorage for objects larger than 1.8GB.

This advanced behavior provides additional HTTP/2 options not present in the Large File Optimization behavior.
