WES7系统启动速度问题

Question

WES7系统在fbwfmgr关闭状态启动速度在30秒左右，但在fbwfmgr开启时，启动速度就有90秒左右，时间是从主板嘀响后开始计时的。求解

Answer 1

你好，

FBWF为操作系统提供更好的弹性和可靠性，它还为操作系统提供无状态的操作并消除损耗。对开机时间的影响不会很大，请检查一下是否还有其他程序影响到了开机时间。

Answer 2

同一个WES7系统环境中，只进行开关写保护测试的。

Answer 3

请透过Event Logo中的，应用程序及服务记录文件

Microsoft-> Windows-> Diagnostics-Performance-Operational

找到 事件标识符为 "100" (100 about system boot up performance issue)

将开启后与关闭后的差异，查看目前的bottonneck 在那个地方，我们再来讨论
