The initial latency when a serverless function or container starts up after being idle, affecting response times.
Cold start happens when a system doesn’t have enough historical data to make good decisions - common in recommendations, new ad accounts, fresh tracking setups, and AI features. Early performance can look unstable because the system is still learning what “good” looks like.
