✅ 99.99% success rate during 300 VU spike — near perfect
✅ p95 = 137ms under sudden burst — barely any degradation vs steady load
✅ 351 req/s throughput — 7.8x higher than the stress test (45 req/s)
✅ Max latency = 675ms — even under spike, no request took over 1 second
⚠️ 1 timeout during ramp-up — normal for connection pool warm-up under sudden burst
🚀 Recovery was instant — server showed no degradation after spike dropped
| Metric | Stress (200 VUs) | Spike (300 VUs) | Verdict |
|---|---|---|---|
| Avg Latency | 48.8ms | 58.6ms | +20% — minimal degradation |
| P95 Latency | 105ms | 137ms | +30% — well within limits |
| Error Rate | 0.00% | 0.00% | Zero errors both |
| Throughput | 45 req/s | 351 req/s | 7.8x more under spike |
| Max Latency | 811ms | 675ms | Better under spike! |
