## 📊 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
|
||
|
||
1. **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
|
||
2. **线性扩展:** 响应时间随并发数增加呈线性增长，符合预期
|
||
3. **失败率:** 1000 并发时出现少量失败 (3.84%)，主要是连接异常
|
||
4. **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
|
||
|
||
1. **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
|
||
2. **建议并发上限:** 500 并发以下可保证 100% 成功率
|
||
3. **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
