持启动耗时、慢启动占比等进行启动指标分析，您可通过慢启动问题列表定位分析 App 慢启动根因。
功能入口
1. 登录 终端性能监控控制台。
2. 在左侧导航栏中选择启动，选择需要查看的业务系统、应用、时间范围分析启动问题。
多维分析
多维分析基于应用版本、系统版本、设备类型、地区、运营商等多个维度分析关键指标，便于您聚焦的现象进行针对性的慢启动根因分析。
慢启动问题列表
慢启动问题列表展示了所有设备的慢启动问题。您可以根据问题异常类型、问题设备 ID、特定函数或文件名快速筛选相关慢启动设备。您还可以单击问题概述查看慢启动问题详情，定位分析 App 慢启动根因。
对于每一个应用冷启动/首次启动样本，Android 系统若启动耗时大于2500ms 为慢启动，iOS 系统若启动耗时大于4000ms 为慢启动对于每一个应用热启动样本，Android 系统若启动耗时大于 1000ms 为慢启动，iOS 系统若启动耗时大于2000ms 为慢启动仅慢启动样本会显示在问题列表中。
指标说明
相关指标说明如下表所示：
指标名称 | 指标说明 |
启动次数 | 应用启动次数。 |
启动耗时 | 启动应用耗时。 |
平均耗时 | 线上样本启动耗时之和/应用启动次数。 |
慢启动次数(占比) | 发生慢启动的次数/总启动次数。 在 Android 端，启动耗时超过2.5s 被默认定义为慢启动。 在 iOS 端启动耗时超过4s 被默认定义为慢启动，阈值可自定义。 |
首次启动 | App 安装后的第一次启动，属于特殊的冷启动。 |
冷启动 | App 结束进程，或退出到后台，进程被系统回收后，再次启动的过程。 |
热启动 | App 切换后台3min 后，从后台被唤起，或从其他 App 界面切换回来的过程。 |
