cold starts

Engines warming up

Cold starts are engine ignitions when the engine hasn't been running and has cooled to ambient temperature: The car struggles with cold starts in winter.

In computing, a cold start is when a system or application launches without cached data or warm-up, causing slower initial response: Serverless functions suffer from cold starts.

The term emphasizes the contrast with warm or hot states where systems are already primed.
