高CPU使用率和简单任务的负载

Question

我知道我的双核AMD Athlon 64 X2 5200一点也不强大，但问题是我明白它在空闲中的使用率(通常)是20%，这对我来说不是个问题，也许它不能做更多的事情……然而，我注意到，有时它是“强大的”，但有时却没有。我不知道这是包相关的内核相关的还是其他的服务.但关键是，对于我所能做的最简单的任务，它需要很快达到80/100%。是的，这显然发生在火狐，但在浏览我的文件时占50/60%是不正常的。

我已经注意到这种行为是不正常的，因为我已经看到它在过去或者在一些罕见的情况下可以做得更多，所以有些事情让我觉得有一个问题导致我的应用程序使用比它应该更多的cpu周期，所有的应用程序，也不仅仅是.或者好像我的显卡没有被使用一样。

我从未对Windows或其他系统进行过MXLinux19.2这样的测试，因此我无法对其进行深入的测试，但是，我有MX默认的LinuxKernel4.19，并且我注意到在使用current时有很小的差别(为了更好)。

一个进程比通常消耗更多的CPU资源是Xorg。我不知道这是否正常，因为它是持久的，总是在5%到15%之间。但是，由于我有一个显卡，我不知道为什么xorg需要这个空间，或者它是否受到影响/影响到其他进程。

我需要为此牺牲我的CPU很多，因为它总是过热，所以在晚上，这一影响是有点减轻。

这可能是由于某些内核补丁或库配置错误造成的吗？请索取您所需的任何其他信息。

Answer 1

也许这个CPU的冷却有问题，并且它正加速到一些比通常更低的MHz？
