调用wmi时如何解决缓慢的加载时间（仅处理器）

我的C＃应用​​程序遇到问题。

我正在使用WMI检索有关我的CPU，GPU和RAM的一些信息。
除了CPU（Win32_Processor）以外，其他所有工具都运作良好且速度很快。
我有一个菜单，每个菜单都有不同的面板（CPU，RAM，GPU）。
最初，我尝试从应用程序的开始加载所有信息，但效果并不理想，加载时间非常长。
其次，我尝试在面板可见时（单击按钮后）加载它们，并且在ram和gpu面板上效果很好。
我对所有代码都使用了完全相同的代码。就是这样：
如果可能的话，我试图使CPU信息的加载速度与其他信息一样快，但是通过搜索和尝试自己的事情，我无法实现它。
我确实意识到，获取所有信息需要一些时间，似乎很奇怪，它需要那么多时间！
PS：单击cpu面板的按钮时的加载时间为3.5秒，而单击“规格”按钮时的加载时间仅显示maxfreq，内核数，数据宽度，线程数，当前电压以及l2，l3大小8秒。
