Serverless Performance: Cloudflare Workers, Lambda and Lambda@Edge

What this post added

This post provides a performance comparison between Cloudflare Workers, AWS Lambda, and AWS Lambda@Edge, demonstrating that Workers are significantly faster due to their global distribution and V8 isolate architecture. It highlights the latency advantages of edge computing for serverless functions, showing Workers are 441% faster than Lambda and 192% faster than Lambda@Edge at the 95th percentile. The post details the technical reasons for this performance difference, including faster spin-up times for isolates, lower memory overhead, and optimized JavaScript API implementations.
