+
+使用并发请求排队功能时，需要正确配置代理（如 Nginx）的超时参数：
+
+- **推荐配置**: `proxy_read_timeout >= max(2 × concurrentRequestQueueTimeoutMs, 60s)`
+  - 当前默认排队超时 10 秒，Nginx 默认 `proxy_read_timeout = 60s` 已满足要求
+  - 如果调整排队超时到 60 秒，推荐代理超时 ≥ 120 秒

+  ```nginx
+  location /api/ {
+      proxy_read_timeout 120s;  # 排队超时 60s 时推荐 120s

+- **企业防火墙环境**:
+  - 某些企业防火墙可能静默关闭长时间无数据的连接（20-40 秒）

 - **并发控制**: Redis Sorted Set实现的并发计数，支持自动过期清理
+- **并发请求排队**: 当API Key并发超限时，请求进入队列等待而非直接返回429
