A startup snapshot is considered cold when it does not contain any function code. We can now create a warm startup snapshot from a cold one by running a warm-up script. Functions exercised by the warm-up script are compiled and its code included in the warm startup snapshot. Side effects caused by the warm-up script does not persist.
