Testing Methodology

  • 30-day testing period (January 2025)
  • Tests across 12 global regions
  • 1000+ cold start measurements per platform
  • Real application workload simulation
  • Cost analysis based on actual usage patterns

30-Day Follow-Up Note

February 2025 Update: After 30 days of production use across multiple client projects, our recommendations remain unchanged. Cloudflare Workers continues to demonstrate superior cold start performance and cost efficiency. However, we did observe that AWS Lambda@Edge's new INIT phase billing has increased costs by approximately 12% for low-traffic functions.
