💡 Key Insights

✅ Zero slow queries — no DB query exceeded 800ms even under 100 VU load
✅ Max query = 524ms — way under the 3s threshold
✅ Deep pagination works — random pages 1-20 all responded fast
✅ Connection pool held up — 100 users × 4 queries = 400 concurrent DB connections
✅ 917 MB response data — DB serialization didn't bottleneck
🚀 Database is production-ready — no indexing or query optimization needed
