large_​file_​optimization

Behavior name: Large File Optimization

The Large File Optimization (LFO) feature improves performance and reliability when delivering large files. You need this behavior for objects larger than 1.8GB, and you should apply it to anything over 100MB. You should apply it only to the specific content to be optimized, such as a download directory's .gz files, and enable the use_versioning option while enforcing your own filename versioning policy. Make sure you meet all the requirements and best practices for the LFO delivery.

Note: Use NetStorage for objects larger than 1.8GB.

To configure partial object caching and HTTP/2 prefetching, see the large_file_optimization_advanced behavior.
