Comparing Serverless Performance for CPU Bound Tasks

In a comparison of performance between Cloudflare Workers and other serverless providers, it was found that Workers are seven times faster than a default Lambda function for CPU-intensive workloads. The PBKDF2 algorithm, designed to be slow to compute, was used as a benchmark for the CPU performance of these services. Cloudflare Workers were also six times faster than [email protected] when tested globally. The results showed that Lambda is slower and more expensive than Workers on a per-cycle basis. Additionally, native code execution in Lambda did not significantly improve its performance compared to JavaScript.
