-# 生产环境部署方案（Issue #91）
-
-## 架构
-
-```
-公网 443 → Nginx(TLS终结/限流/HSTS) → 127.0.0.1:8000 app(FastAPI, 非root, read_only)
-                                      → postgres(数据卷 pgdata)
-```
-
-## 步骤
-
-1. **服务器初始化**：`sudo bash deploy/production/server-setup.sh`
-   （系统更新、Docker、防火墙仅 22/80/443、SSH 禁 root/密码登录、部署用户 deploy）
-2. **域名与证书**：将 `wms.xayunmei.com` A 记录指向服务器，证书放入
-   `deploy/production/certs/`（wms.crt / wms.key）。
-3. **启动**：`REGISTRY=... IMAGE_TAG=<commit> docker compose \
-   -f docker-compose.yml -f deploy/production/docker-compose.override.yml up -d`
-4. **日常部署**：`bash scripts/deploy.sh <commit_sha>`（自动拉取/滚动更新/健康检查/回滚）。
-
-## 备份策略
-
- `deploy/production/backup.sh`：pg_dump 每日全量 + sha256 校验，保留 30 天，
-  可选 rsync 异地同步（`BACKUP_REMOTE` 环境变量）。建议 crontab：`0 2 * * * /opt/wms/deploy/production/backup.sh`
-
-## 安全基线
-
- 容器非 root + 只读文件系统 + 资源限额（2C/2G）+ json-file 日志轮转
- 应用端口仅绑定 127.0.0.1，对外仅 443；HTTP 强制跳转 HTTPS；TLS1.2+；HSTS
- API 限流 20r/s（burst 40），安全响应头齐全

+# 性能压测方案（Issue #94）

+## 范围

+1. **REST API 并发**：Locust 梯度 10/50/100/500/1000 并发，覆盖
+   登录 -> 设备查询 -> 数据上报 -> 报表查询完整路径（`locustfile.py`）
+2. **数据量**：百万级抄表/营收记录下的分页查询与报表聚合（结合 `db/` 种子数据，
+   关注慢查询日志 > 500ms 的语句并补索引）
+3. **WebSocket 长连接**：`websocket_stress.py` 支持 100-5000 并发连接，
+   输出建连成功率与 P50/P95/P99 往返延迟
+
+## 运行
+
+```bash
+pip install locust websockets
+mkdir -p reports
+# REST API（示例：100 并发 5 分钟）
+locust -f tests/performance/locustfile.py --host http://127.0.0.1:8000 \

+| API P95 延迟（100 并发） | ≤ 300ms |
+| API 错误率（500 并发） | ≤ 0.5% |
