The startup course have to be indicated by the most crucial-Course manifest header in its manifest file.

The subsequent illustrations demonstrate how you can set the maximum permitted sizing of allotted memory to 80 MB employing different models:

Forces stack scanning of Energetic ways to aggressively take away unused code when just the supplied share on the code cache is cost-free. The default worth is ten%.
