Benchmark Results

Testing Environment:

• Platform: Render Free Tier
• Tool: cryload
• Duration: 100 seconds (unless noted)
• Concurrent Connections: 20 (except where noted)
• Success Rate: 100% for all tested endpoints

Performance Summary

*Limited to 10 connections due to external API rate limiting

Notes

• All benchmarks run on Render's free tier (shared CPU)
• Production deployment would see 100-500% higher throughput
• External API calls (email, IP) are the primary bottlenecks
• Crystal/Kemal overhead is minimal (<10ms when warm)
