  90%     68ms
  95%     75ms
  99%     78ms
 100%     84ms

✅ 结果: 良好 - 零失败，性能稳定

场景 3: 1000 并发，10000 请求

Concurrency Level:      1000
Time taken for tests:   1.273 seconds
Complete requests:      10000
Failed requests:        384 (3.84%)
   (Connect: 0, Receive: 0, Length: 192, Exceptions: 192)
Requests per second:    7858.18 [#/sec] (mean)
Time per request:       127.256 [ms] (mean)
Transfer rate:          14993.12 [Kbytes/sec] received

Connection Times (ms)
              min  mean[+/-sd] median   max
Connect:        0   53   8.9     53      74

⚠️ 结果: 可接受 - 出现 3.84% 失败率，但整体性能仍稳定

静态资源测试: game.js (500 并发，5000 请求)

Concurrency Level:      500
Time taken for tests:   0.670 seconds

Transfer rate:          51677.50 [Kbytes/sec] received

✅ 结果: 优秀 - 静态资源传输效率高

📊 性能分析

吞吐量对比

场景	请求/秒	失败率	平均响应时间	P95 响应时间
100 并发	7,723	0%	12.9ms	14ms
500 并发	7,467	0%	67.0ms	75ms
1000 并发	7,858	3.84%	127.3ms	132ms

关键发现

吞吐量稳定: 服务器在不同并发级别下均保持约 7,500-7,800 请求/秒的吞吐量
线性扩展: 响应时间随并发数增加呈线性增长，符合预期
失败率: 1000 并发时出现少量失败 (3.84%)，主要是连接异常
静态资源: nginx 对静态文件的传输效率优秀 (51MB/s)

✅ 结论

性能评级: A

蛇游戏服务器在正常负载下表现优秀：

✅ 低并发 (100): 完美表现，零失败，响应时间 < 15ms
✅ 中并发 (500): 表现良好，零失败，响应时间 < 85ms
⚠️ 高并发 (1000): 可接受，少量失败 (< 4%)，响应时间 < 145ms

建议

当前配置适合生产使用 - 对于单机游戏服务器，性能完全足够
建议并发上限: 500 并发以下可保证 100% 成功率
优化方向 (可选):
- 启用 nginx 连接保持 (keepalive)
- 配置静态资源缓存头
- 考虑启用 gzip 压缩
