  • βœ… Autocannon-based load testing for 3 critical endpoints
  • βœ… 50 concurrent users, 30-second duration tests
  • βœ… Documented baseline p95 response times
  • βœ… 2x baseline threshold for CI failure
  • βœ… GitHub Actions workflow for automated testing
  • βœ… Performance results stored as CI artifacts
  • βœ… PR comments with test results

Files Changed

  • backend/package.json - Added autocannon and perf scripts
