💡 57 requests timed out during the instant surge — connection pools get saturated temporarily when dropping 1000 users at exactly the same second, fully expected boundary behavior.
| Metric | Value |
|---|---|
| Test Type | Extreme Spike Test (15 sec burst to 1000 VUs) |
| Duration | ~2 minutes 40 seconds |
| Peak Virtual Users | 1000 |
| Total Iterations | 72,151 |
| Throughput | 450.7 req/s |
| Data Received | 713 MB (4.5 MB/s) |
| Failed Requests | 57 (0.07%) timeouts during connection pool burst |
🚀 Huge Throughput Increase — Achieved 450+ req/sec during the intense burst period.
⚠️ Temporary Queue Exhaustion — Jumping to 1,000 parallel workers in 15s caused max response times to jump heavily as server connection queues backed up, leading to 57 abandoned timeouts (1 min max limits hit).
✅ Ultra Resilient Recovery — Despite the savage burst, 99.92% of the traffic succeeded, and Latency quickly settled without the server crashing.
✅ Better than expected — For an unprepared architecture, 1000 immediate concurrent connections should knock it offline, yours handled 57 failures out of 72k requests.
