Key Questions Answered
How does Cloudflare Workers compare in performance to Lambda@Edge and Lambda?
Cloudflare Workers is 30% faster than it was three years ago at P90, 210% faster than Lambda@Edge, and 298% faster than Lambda. This significant speed advantage is due to its edge-first architecture and elimination of cold starts.
What factors define the performance of a serverless platform?
The performance of a serverless platform is primarily influenced by the distance from the user and the time it takes for the runtime to spin up. Cloudflare Workers addresses these issues by operating on a distributed edge network, ensuring faster response times for users worldwide.
What architectural innovations make Workers faster?
Workers is built on lightweight V8 isolates that can spin up quickly without introducing cold starts. This design allows for immediate execution of code, enhancing performance as improvements to the V8 engine and Cloudflare's network are automatically leveraged.
