This benchmark is bun based, this is an aim to test with bun fastest frameworks.
Results
- OS: macOS 15.4.0
- Host: MacBook Pro (12 Threads)
- Memory: 32 GB
- Shell: bash 5.1.16
- Tool: oha 1.14.0
This benchmark compares Jetpath, ElysiaJS, and Bun.serve under high-concurrency load.
how to run this benchmark

Server Performance Comparison (JETPATH vs ELYSIA vs BUN)
Benchmark Details:
- Tool: oha
- Workload: 30s duration per round (3 rounds aggregated)
- Concurrency: 256 concurrent connections (tuned for 12-thread CPU)
- Warm-up: 10,000 requests @ 50 concurrency
- Servers: JETPATH (:3000), ELYSIA (:3001), BUN (:3002)
Key Metrics Summary
| Metric | JETPATH (localhost:3000) | ELYSIA (localhost:3001) | BUN Native (localhost:3002) |
|---|---|---|---|
| Success Rate | 100.00% | 100.00% | 100.00% |
| Requests/Second | 38,495 | 39,082 | 48,246 |
| Average Latency | 8.12 ms | 6.22 ms | 5.30 ms |
| Median (50%) Latency | 7.72 ms | 5.85 ms | 5.06 ms |
| 95% Latency | 9.30 ms | 7.05 ms | 5.95 ms |
| 99% Latency | 12.45 ms | 9.40 ms | 7.50 ms |
| Slowest Latency | 106.7 ms | 102.4 ms | 75.3 ms |
Conclusion
All three frameworks managed to maintain a 100% success rate under a steady load of 256 concurrent connections. The benchmark setup (lifecycle management, warm-ups, and cooldowns) ensures that these results are not skewed by resource contention or thermal throttling between runs.
