收集 .NET CSM Statistic/Avg execution time 性能计数器(毫秒)

摘要

如果每个定义时段内浏览器上的网页加载平均请求时间超过监视器阈值，则实例状态将变为不正常。

原因

在客户端性能事件的平均持续时间超过所配置的监视器阈值时，将生成事务性能警报。

过长的网络请求时间可能由不均衡的网络所引起。

复杂或低效的源代码可能会导致服务器处理时间很长。

大页面或大量的 java 脚本都可能会导致页面加载时间性能问题。

执行时间很长的 JavaScript 处理程序可能会导致 Window.OnLoad 较长的性能问题。

解决方法

页面加载调用时间长的原因通常包括，网络不平衡、服务器处理时间长、页面加载或 Window.OnLoad 时间较长。
