Ground truth on Uncooked vs Cooked Performance

The project I’m working on won’t be distributed widely, more of a personal demo project, and there’s a specific reason I want to keep the project uncooked. I’ll be collecting some performance data to compare the two, but I was wondering if there are any additional performance or functionality related downsides to running the game uncooked (launching from a UE4editor.exe shortcut with the launch option to open the project as a game) versus packaging the game and running the executable. My initial guess for running uncooked is increased overhead, longer initial load time, additional memory usage, and potentially worse performance. Is there anything to be expected beyond that?

Thanks ahead of time.
