Cold Starts & Warmups
Understand and mitigate the impact of cold starts on serverless functions for faster responses.
Edge Performance Challenges
When building applications at the edge, performance is critical. Users expect instant responses, and any delay can lead to a poor experience.
Serverless functions, like Cloudflare Workers, bring code closer to users, but they also introduce unique performance considerations. One of the main challenges is the concept of a cold start.
Understanding Cold Starts
A cold start is the delay experienced when a serverless function is invoked for the very first time, or after a period of inactivity.
It's essentially the time it takes for the serverless platform to prepare the execution environment for your code. Think of it like waking up a sleeping computer before it can run a program.
